Where can you find a ruby? How much does a real ruby ​​cost and where can you buy it? Methods for home conditions

At great depths, under great pressure and temperature, minerals of amazing beauty - rubies - are born. Their formation varies depending on the specific deposit where rubies are mined, but most often it occurs at a temperature of 450 degrees and at a depth of up to 30 km. As a result of transformation, sedimentary rocks turn into metamorphic rock.

Despite the fact that ruby ​​deposits theoretically exist on all continents except Antarctica, the extraction of the precious gem is not carried out everywhere. The most famous ruby ​​deposits at the moment are located in southeast Asia (Burma), on the island of Sri Lanka (Ceylon) and in Thailand.

Burmese rubies are an undeniable ideal; they are superior to other specimens in quality and beauty, and accordingly, they are more expensive. It was there that the largest and most famous ruby ​​was discovered at one time, whose weight reached four hundred carats. True, in its original state it did not survive to this day - it was split into three parts.

But now, unfortunately, the Burmese ruby ​​deposits are almost completely depleted. It’s not surprising, since for so many years they have been the source of the best gems in the world! The most promising direction where ruby ​​is currently mined is India. The famous Kashmir mines in India, which supply the jewelry market with the best sapphires, can also provide the best rubies. Red rubies of excellent quality have already been discovered there, and the deposits of the island of Sri Lanka have already become famous for their rare star gems.

Deposits of rubies and sapphires - mining of precious stones

On the picture. Deposits of Sri Lanka - extraction of precious stones from flowing waters in the middle of the 20th century.

Jewelry rubies are formed mainly during contact metamorphism of dolomitic limestones under the influence of granites. In such cases, dolomite marbles serve as host rocks. However, the ruby ​​content in such primary deposits is too low for industrial development. Rubies are mined mainly from alluvial placers. The high density of ruby ​​makes it possible to enrich river sand and pebble deposits by washing; From the resulting concentrate, the rubies are then selected by hand.

Extraction methods today are as primitive as they were hundreds of years ago. The owners of ruby ​​mines, as a rule, are Western companies with limited participation of local entrepreneurs. More or less significant ruby ​​deposits are known only in Burma, Thailand, Sri Lanka and Tanzania. The most important of them are in Upper Burma, near Mogok. The layer containing rubies lies here a few meters from the surface and is developed through pits, ditches and shafts. But only about 1% of mined rubies are of gem quality. True, rubies here often have the color of “pigeon’s blood.” Large stones are very rare.

Thai rubies are usually brownish. They are mined southeast of Bangkok, in the Changvada district, from clay gravel. The mining mines here reach a depth of 8 m. In Sri Lanka, the deposits are located in the southwestern part of the island, in the Ratnapura region. Rubies from these placers (called illam in the local dialect) are usually strawberry in color. Rubies are often mined here directly from the bottom of rivers - from sands and pebbles. Since the 50s of the 20th century, decorative green rock (zoisite amphibolite) with fairly large, although mostly opaque, rubies has been mined in Tanzania. Only a few crystals here are suitable for cutting. Rubies were also found in the upper reaches of the Umba River, in the northeast of the country. They have a purple or brownish tint.

Minor deposits of rubies are found in Afghanistan, Australia (Queensland), Brazil, Kampuchea, Madagascar, Malawi, Pakistan, Zimbabwe and the USA (North Carolina). Small deposits of ruby ​​and sapphire are also known in Switzerland (Tessin), Norway and the CIS (Urals, Pamirs). Ruby is one of the most expensive jewelry stones. Large rubies are rarer than comparable diamonds. The largest gem-quality ruby ​​weighed 400 carats; it was found in Burma and split into three parts. Among the world-famous rubies of outstanding beauty are the Edward Ruby - 167 ct (British Museum of Natural History, London), the Riva star ruby ​​- 138.7 ct (Smithsonian Institution, Washington), the De Long star ruby ​​- 100 kar (American Museum of Natural History, New York), "Peace" ruby ​​- 43 ct, which received its name due to the fact that it was found in 1919, at the end of the First World War.

Numerous rubies adorn royal regalia and ancient family jewels. However, many of them, as a result of recent research, have been “exposed”, turning out to be red spinel. Among them are the "Black Prince's Ruby" in the British crown and the "Timur's Ruby" in the breast chain, also belonging to the English crown jewels. The teardrop-shaped spinels of the Wittelsbach Crown, made in 1830, were also long considered rubies.

Currently, rubies are usually cut in the countries where they are mined. Cutters, trying to preserve as much of the stone as possible, do not always maintain its proportions, so many stones later have to be re-cut. Transparent rubies are given a step or brilliant cut, while less transparent ones are cut into cabochons.

A lot of fake rubies end up on the jewelry market, especially glass imitations and doublets with the top part made of garnet and the bottom part made of glass, or with the top part made of natural sapphire and the bottom part made of synthetic ruby. There are many misleading trade names in circulation to this day: for example, Balas ruby ​​(spinel), Cape ruby ​​(garnet), Siberian ruby ​​(tourmaline). Ruby can be confused with garnets - almandine and pyrope, fluorite, zircon-hyacinth, spinel, topaz, tourmaline.

Since the 1900s, synthetic jewelry rubies have appeared, similar to natural ones in composition, physical and especially optical properties. However, they can be distinguished by inclusions, and also due to the fact that, unlike natural rubies, they transmit ultraviolet rays. For watch and reference stones in devices, as well as for solid-state lasers and other technical needs, exclusively synthetic rubies are now used.

The huge and growing difference in price between natural and synthetic rubies makes methods for their reliable identification particularly important. The easiest way to confuse a ruby ​​with a red spinel: both stones are similar not only in color, but also in hardness, density, light refraction (spinel is only a little softer and lighter, has a slightly less bright shine), however, unlike ruby, it is optically isotropic, which means labor is established using a polarizing microscope.

In the CIS, ruby ​​deposits were discovered only in the middle of the 20th century. This is primarily the Makar-Ruz deposit in the Polar Urals, confined to the ultrabasic Rai-Iz massif, as well as finds of ruby ​​in the peculiar pegmatites of the Pamirs. Along with opaque red corundum, both deposits contain transparent gem-quality ruby ​​crystals.

The host rocks of sapphire deposits are marbles or basalts. They are also formed in pegmatites, but are mined mainly from alluvial placers or weathering crusts, less often from bedrock. Development methods are extremely simple: manually driven pits or pits and eroded slopes allow the development of sapphire-bearing formations located at depth.

Clay, sand and gravel are separated by washing; Sapphires accumulate due to their high density. Finally, the sapphires are manually selected and classified according to quality. Sapphire is much more widespread than its closest relative, ruby, since the chromophore of sapphires is iron, and not the rare chromium that colors rubies.

Industrially significant sapphire deposits are now located in Australia, Burma, Sri Lanka and Thailand. Australian deposits in Queensland have been known since 1870. The host rocks there are basalts, from the weathered upper layer of which sapphires are extracted by washing. Their quality is low. The deep blue color of these stones becomes inky, greenish or even almost black in artificial light. Lighter stones also have a green tint. Black star sapphires have recently been discovered. Associated minerals of Australian sapphires are quartz, pyrope, topaz, tourmaline, zircon. In 1918, good quality blue sapphires were discovered in New South Wales. In recent years, these deposits have apparently become very productive. In Upper Burma, near Mogok, alluvial placers are mined, containing, along with sapphire, also ruby ​​and spinel. Their parent rocks are pegmatites. In 1966, the largest star sapphire was found here - a crystal weighing 63,000 carats (12.6 kg!).

On the island of Sri Lanka, sapphires have been mined since ancient times. The deposits there are located in the southwestern part of the island, in the Ratnapura region. The host rocks are remnants of dolomitized limestones in granites or their interlayers in gneisses. Placers of river pebbles with a thickness of 30-60 cm (in the local dialect "illam"), located at a depth of 2 to 10 m, are being mined. The sapphires in them are mainly light blue, often with a violet tint. In addition, there are also yellow and orange varieties of the Padparadscha type and, along with them, green, pink, brown and almost colorless stones, and finally, star sapphires and cat's eye sapphires. Associated minerals are very numerous: apatite, garnet, quartz, cordierite, topaz, tourmaline, zircon, spinel, epidote.

The island of Ceylon may well lay claim to the status of Paradise on Earth. For Sri Lanka (as this island state is called today), precious stones are a serious budget item, providing about 5% of the republic’s GDP. The undisputed “king” of Ceylon stones is blue sapphire. Sri Lanka is a state that is actively developing the mining of various precious stones and their processing. Sri Lanka supplies the world market with both raw precious stones and their processed products - refined raw materials, jewelry inserts - faceted precious stones, as well as jewelry with them. The market is based on the famous Ceylon sapphires, including fancy colored and star sapphires. But only blue Ceylon sapphire is the national stone of Sri Lanka.


Sapphire mining in Sri Lanka today, at the beginning of the 21st century

There are two sapphire deposits in Thailand: one (Bang Kha Cha) is located near Chanthaburi, 220 km southeast of Bangkok, the other (Bo Phloy) is near Kancha Naburi, 120 km northwest of Bangkok. The host rocks are marbles or basalts. Deposits confined to placers and weathering crusts are being developed. Satellite minerals: garnet, ruby, zircon, spinel. The sapphires here are of good quality and come in a variety of colors, including star-shaped ones. The stones are a deep blue color, however, usually with a greenish tint.

Kashmir sapphires (India) are more prized than others. The deposits there are located at an altitude of 5000 m (Zanskar Range in the Himalayas) 200 km southeast of Srinagar. They have been in use with varying success since 1880 and are now apparently exhausted. Sapphires there were mined from a highly kaolinized pegmatite vein embedded in crystalline marbles. From the grit of these pegmatites, sapphires of thick cornflower blue, often with a silky tint, were extracted. Burmese sapphires are often passed off as Kashmiri.

In 1894, sapphire deposits were discovered in the state. Montana (USA), confined to an andesite dike. The stones were extracted both from the dike itself and from the crushed stone formed during its weathering. The colors of Montana sapphires are very varied, often being pale blue or steel blue. Development of the field was stopped at the end of the 20s of the 20th century, but then resumed again.

Sapphire deposits are also known in Brazil (Mato Grosso), in the west of Kampuchea, in Kenya, Malawi, Zimbabwe and, more recently, in the north of Tanzania. Single finds of star sapphires occur in the north of Finland (in Lapland).

Large sapphires are rare. Sometimes, like famous diamonds, they are given their own names. The American Museum of Natural History (New York) owns the Star of India, probably the largest cut star sapphire (536 ct), as well as the black Midnight Star sapphire (116 ct). The Smithsonian Institution (Washington) acquired the Star of Asia star sapphire (330 ct). Two famous sapphires (St. Edward's and Stuart's) are among the British Crown Jewels. In the USA, sculptural portraits of US presidents: Washington, Lincoln and Eisenhower are carved from three sapphires, weighing approximately 2000 carats each.

Many stones are similar to blue sapphire: benitoite, kyanite, cordierite, tanzanite, topaz, tourmaline, zircon starlite. spinel; They also imitate it with blue glass. There are many trade names that mislead the buyer: for example, Brazilian sapphire is called blue topaz, oriental sapphire - blue tourmaline.

At the beginning of the century, they learned to grow synthetic sapphires, whose properties are very close to natural ones. Since 1947, synthetic star sapphires of gem quality have also been produced.

The Diamond Fund's collection contains blue Ceylon sapphires that are unique in beauty and weight; one of them (200 karat) is mounted in the cross of the Russian Empire, the other (258 karat) is inserted into a brooch. Manifestations of blue sapphire in the CIS, associated with syenite pegmatites of the Ilmen Mountains in the Urals and with napheline syenite pegmatites of the Khibiny massif on the Kola Peninsula, are small and, in addition, can serve as sources of low-quality cutting raw materials, suitable only for the production of small stones of the “spark” type.

The delightful color of ruby, exquisite shade, amazing shine and high quality leaves no one indifferent! There are many legends and exciting stories about it, so it is not surprising that every woman would like to become the owner of such a precious stone. Since this stone is one of the rarest, it becomes even more attractive and charming in the eyes of women. But few people think about its origin and place of extraction, although this is important in its value and quality.

Where is ruby ​​mined in the world?

Ruby mining is not carried out in every country. They are obtained in Burma, and their peculiarity is their amazing color: deep red with a bluish tint. For many years this was believed to be the only location of the ruby. However, over time it was discovered in other countries: Thailand, Sri Lanka and Vietnam. The advantage of the stone found in these countries is its piercing shine, which does not fade or lose strength in any light.

Small amounts of ruby ​​are also found in Madagascar, Pakistan, USA, Brazil, Australia, Colombia and Tanzania. Even in Russia deposits of this precious stone have been found. For example, in the Sigangoy field and in the Urals.

A gemstone obtained in different countries, even with the same processing, has distinctive features.

After mining, the gems are sent to Thailand, Israel or Europe. High-quality cutting of rubies takes place there. This process consists of filling voids in the stone with glass mass, which make up from 30 to 70% of the ruby. The next stage is considered “natural healing,” which involves removing mineral inclusions through heat treatment. After this, “artificial healing” begins, with the help of which all inclusions are removed and the cracks are glued together. The process of cutting a ruby ​​is quite difficult and requires skill, experience and accuracy. The final result is an indicator of the quality and value of the ruby.

Features of ruby ​​found in different countries

  • The Burmese ruby ​​has a “pigeon blood color”, which makes this stone popular and expensive.
  • The Thai ruby ​​is called Siamese ruby ​​due to its brownish hue. Its value is very similar to that mined in Burma.
  • Rubies, which are found in Sri Lanka, are distinguished by a harmonious combination of red color and light shades. As a result, the stone turns out to be the color of ripe raspberries.
  • Although African rubies are not considered the most valuable, stones mined in Kenya and Tanzania shimmer and change color when exposed to light.
  • Vietnamese ruby ​​has a purple hue, which makes it special and attractive.

Due to such features, as well as the rarity and difficulty of mining, ! Its presence on an accessory is an indicator of luxury and wealth. It is the ruby ​​that adorns crowns, wedding necklaces and expensive dresses that make you fall in love at first sight.

And today, a natural ruby ​​in a collection of stones or jewelry is the pride and heritage of its owner. But not everyone can recognize the truly noble nature of the mineral right away. We will talk further about how to distinguish a ruby ​​from a fake with an unprofessional eye.

Not everything that is ruby ​​is red

Not only jewelry nanocrystals, but also other natural minerals can be fake rubies. Here is a large list of those stones that particularly cunning suppliers and manufacturers can pass off as real scarlet corundum:

  1. Pink sapphire is a stone from the same mineralogical family.
  2. Almandine, pyrope, is the hardest of the garnets. It bears the historical name “Alabanda ruby”.
  3. Pink spinel, called "bale ruby".
  4. Red spinel, also known as ruby ​​spinel.
  5. Crystals of pink topaz, which have the trade name “Brazilian ruby”.
  6. Cuprite or "copper ruby".
  7. Red tourmaline - rubellite, has the commercial name "Siberian ruby".
  8. The infamous “Geneva ruby” is a synthetic crystal obtained in Europe at the end of the 19th century. The secret has not yet been revealed, but most are inclined to believe that it is an alloy of powder and crumbs of natural corundum.
  9. Red sphalerite or ruby ​​blende is a rock that can be difficult to recognize. Only rare crystals that can be cut are suitable for counterfeiting gemstones. They are mined in Spain.
  10. Vernel ruby ​​is a synthetic stone.
  11. Rose quartz crystals - “Anconian ruby”.
  12. Composite ruby ​​is a skillful alloy of natural stone and glass. The purpose of such manipulation is to increase the weight, and accordingly, the price of the original real crystal.
  13. Glass painted in rich red tones is the cheapest imitation, short-lived and easily recognizable.

As you can see, there are many minerals and artificial materials that can be mistaken for a genuine gem with the naked eye. Therefore, it is so important to know the ways and techniques to help distinguish a natural ruby ​​from an artificial one.

“Garnet deception”: how to determine the authenticity of a ruby

Usually, a variety of garnet – pyrope or almandine – is passed off as a genuine stone. With a set of certain knowledge and tools, finding out the truth will not be difficult. Here are some tips on how to distinguish a ruby ​​from a garnet:

  • If it is possible to use a special Heidinger magnifying glass, then minerals can be distinguished based on dichroism. In static polarized light, corundum crystals will change color to a darker one. This is clearly visible when changing the angle of view. Garnets do not have this property.
  • In ultraviolet rays, it is even easier to identify a real ruby: it luminesces with an orange glow. In pyropes and almandines such a glow is not observed.
  • An ordinary magnifying glass is also a good helper, as long as the lighting is of high quality. If you look closely at a ruby ​​crystal under such conditions, you will clearly see needle-shaped inclusions. And for a stone in the shape of a cabochon, they also give the optical effect of a star of 6 rays.
  • The uniformity of the natural color of stones is an important characteristic in their distinguishability. Natural stone is not uniform, whereas garnet has an even color distribution.
  • The strength of ruby ​​is very high; its crystal can scratch, for example, topaz or crystal. Whereas garnet is capable of “inheriting” only on the crystal surface.
  • The sparkle of a ruby ​​is akin to that of a diamond, while garnet has a soft, oily sheen.

Here are the main features that distinguish gems that are similar in appearance but completely different in mineral type. These tips are quite applicable not only to garnet imitation, but also to other natural stones that they try to pass off as natural rubies.

Nanocrystal, glass or natural gem: how to distinguish a fake

Data-lazy-type="image" data-src="https://karatto.ru/wp-content/uploads/2017/10/kak-otlichit-rubin-ot-poddelki-2.jpg" alt="( !LANG:artificial ruby" width="260" height="259">!}
Synthetic analogues of stone and glass fakes are much more often used to replace natural gemstones. But there are key points based on the properties of the natural mineral and allowing you to understand how the imitation differs from the original.

Thus, artificially created crystals have a perfect shape, while natural stones are characterized by natural individuality in the form of natural defects, bubbles, inclusions, etc. Also, a real gem has some weight, unlike ordinary glass. If you rock the stone a little in your palm, you can feel its mass and heaviness.

Methods for synthesizing artificial crystals

Artificial crystals have been produced on an industrial scale since the beginning of the 20th century. Until now, this technology is based on 4 methods:

  1. Vernel and Czochralski methods. They make it possible to obtain cheap red corundum in large quantities. Gems grown according to these principles are easily recognized by their curved growth lines.
  2. The other two production methods, flux and hydrothermal, are very expensive. Their peculiarity is that it is difficult for a non-specialist to distinguish synthetic flux or hydrothermal corundum from natural stones. Therefore, when purchasing a very expensive specimen, it is better to seek the help of a qualified gemologist.

Methods for home conditions

One of the well-known original techniques for checking the naturalness of a stone at home is its contact with milk. You just need to immerse the gem in the liquid and wait. The natural mineral will give the milk a pinkish tint. The fake will not affect the color in any way.

Another good tip for identifying a real ruby ​​is to keep the gem on your skin for a while. Experts are not kidding when they recommend placing a pebble on your eyelid - this is the most temperature-sensitive area. The analogue will quickly heat up, the natural mineral will give off coolness for a long time.

This advice and knowledge has been tested by experience. But so that you don’t have to pick up a magnifying glass and dip a gem in milk, it’s better to understand: good stones (and ruby ​​is undoubtedly one of them) and mass market are incompatible concepts. Each expensive natural crystal is an individuality that does not tolerate flow and conveyor belts. Therefore, the price of a real ruby ​​cannot be burdensome. And its purchase must be accompanied by a certificate from a reputable gemological center.

Ruby is a mineral, a representative of precious stones. It is a type of natural corundum, one of the hardest minerals on Earth. It has absolute hardness and is in second place after diamond. Endowed with anisotropic optical properties. The admixture of chromium creates a red color. Stones with this color are called rubies. Corundums with blue color are sapphires. Ruby is considered the patron saint of strong and brave people.

The richest ruby ​​deposits in the world

These amazing stones are born at great depths under high temperature and pressure. Theoretically, rubies can be found anywhere on our planet. But you can’t get it everywhere. The most famous and gem-rich places are ruby ​​deposits in:

  • Burma;
  • Sri Lanka;
  • Thailand.


Rubies from each deposit differ from each other in density and specific gravity, light refraction, and transparency. Specimens from Burma are ideal minerals, their quality and beauty are an order of magnitude higher than stones from other deposits. Therefore, their cost is much higher. Now the Burmese deposits are practically empty; for the entire time of their existence, there are no more worthy specimens of rubies left to supply to the jewelry markets of the world.

Today, India occupies a worthy first place in the extraction of the precious mineral. The Kashmir deposit produces sapphires of excellent quality. There are also red rubies. It is hoped that this deposit will become a center for the extraction of these varieties of corundum.

Other famous ruby ​​deposits

The island of Ceylon (Sri Lanka) is famous for its deposits of rare specimens of star-shaped gems, and is on the same level as Burmese rubies.

In Thailand, they are developing a deposit with precious minerals, which, although of lower quality, are also included in the group of precious stones that are valuable and in demand on the market.

In many countries in Africa, Asia, Australia, America and European countries, painstaking work is also underway to extract precious gems from the bowels of the Earth, but so far the stones that come across do not reach the border, crossing which they will receive worldwide recognition. Most specimens cannot be cut and are widely used for industrial purposes.

The owner of the ruby ​​deposit is a Western company. Local enterprises have a small share in this huge mechanism and carry out mainly labor-intensive work. After extraction, the raw ruby ​​is sent for cutting to the European Union, Israel or Thailand. This is a complex procedure that requires specialists to have enormous experience and the highest precision. The quality of the product and its final cost depend on how the ruby ​​is cut.

Gradation by quality and price of rubies

The fiery red ruby ​​is rightfully the epitome of perfection. Jewelry connoisseurs rate this stone quite highly. The cost of some large specimens sometimes exceeds the cost of diamonds of the same size.

Rubies are:

  • red with dark and light shades;
  • pink;
  • scarlet;
  • purple.




The precious crystal can have orange, purple and black glitter.

There are stones of amazing shape and color intensity. There are slightly cloudy specimens and opaque ones, star-shaped and with a cat's eye effect. Some types of crystals are not cut, but polished, giving them a convex shape. Burmese rubies are still famous for their particularly beautiful and expensive specimens. The price of one carat can start from 50 and reach 5,000 US dollars.

Indian corundums differ from stones from other deposits in their light shade and the presence of cracks and specks in the stone. Because of this, the cost of stones is much lower.

Tanzanian rubies are particularly dark and monochromatic. This classifies the mineral as second grade. But some stones have a bright garnet hue and after cutting, garnet rubies become worthy of attention.

Precious crystals from Kenya, Madagascar, and Afghanistan have amazing reflections and effects, although they are much less expensive.

Modern technologies make it possible to grow red corundum artificially. The resulting crystal is not inferior to natural ruby ​​in appearance and quality. The synthetic mineral is widely used for industrial purposes. To distinguish a natural ruby ​​from a man-made one, just dip it in milk - the surface turns pink.

Features of ruby ​​mining

Precious rubies are mined on an industrial scale in alluvial placers, where the crystal density is very high. The extraction of rubies and sapphires is done manually. The method of mining rubies is as simple as it was hundreds of years ago. First, entrepreneurs must obtain a license, which costs a lot of money.

They dig holes that eventually develop into shafts and adits. Pumps installed on the surface constantly pump out water. As soon as the pump stops, the water will quickly begin to flow and fill the shaft. Air is forced into the shaft.

The rock, which is mostly clay, is raised to the surface in baskets, where it is washed and precious stones are found. You can dig for months and still find nothing. People in such fields work in families.

Some are exhaustively digging, others are processing the found specimens of stones. This is due to the fact that the untreated rubies found are semi-precious specimens, and do not provide an idea of ​​the actual value of the stone before it is processed. If the ruby ​​turns out to be pure, then a significant amount of money can be obtained from its sale.

Mining rubies is very hard and sometimes dangerous work. Crystals are mined in rocks at depths sometimes reaching 30 meters. But for the poor population it is the only way out and way of survival.

Gemstone processing

Before being put up for sale, all natural specimens undergo special corrective processing:

  • thermal effect on the crystal;
  • To obtain a rich red color, ruby ​​is treated with beryllium;
  • Transparent liquid glass is used to fill cracks and voids in the body of a ruby.

The crystal is refined, giving it a smooth surface and a rich shade.

When submitted for correction, a ruby ​​may have minor defects that do not particularly affect the color of the stone or its transparency. Such specimens of the mineral are called pure specimens.

Another type of gemstones that have significant cracks and inclusions are classified as impure stones. Both groups of crystals are subject to the correction procedure. Natural corundums become attractive and go on sale. The price of the product will be significantly lower than a natural, unprocessed and high-quality specimen.

Where are rubies used?

The area of ​​application of synthetic ruby ​​is industry. Due to its strength, it is used on the surface of sandpaper and in watch mechanisms. Synthetic rubies are used as an active medium in the manufacture of lasers.

In folk medicine, ruby ​​is credited with medicinal properties. Carrying it with you helps you sleep well, strengthens your eyesight, and reduces back pain. Asian sages considered ruby ​​to be a healer of heart disease, as well as capable of improving brain function and giving energy to a person.

Alternative medicine classifies ruby ​​as a remedy that can prevent epileptic strokes and restore the nervous system after stress.

Many peoples of the world attribute magical properties to the mineral.

Ruby is the king of gems. And the main purpose of this precious, magnificent stone is to be used as an expensive decoration in combination with other precious metals and minerals.
