What properties does green pomegranate have?

Demantoid gemstone is a variety of the mineral andradite, which is part of the garnet group. This is a very rare and most expensive variety of pomegranate. The color of this andradite garnet is green, often with yellowish or brownish tints, rarely with a blue tint. The most valuable shade is rich green without any hint of yellowness. The green color characteristic of this gem is associated with the content of chromium and iron; titanium gives yellow shades. The stone was first found in the mid-19th century in Russia, in the Urals. Now mining is carried out in other countries, but Ural samples are valued more than others. The cost of demantoid from the Urals is several times higher, for example, than from Namibia or Madagascar. Natural Ural demantoid is a kind of established brand, just like a ruby ​​from Burma or an emerald from Colombia. A characteristic feature of Ural crystals is the presence in them of beautiful fibrous inclusions of bissolite in the form of a “horse tail”. The presence of ponytail inclusions can even increase the cost. Good quality demantoids are in great demand on the world market. For example, the Japanese are simply “crazy” about Russian minerals from the Urals. It is a pity that cut Ural specimens very rarely exceed 1-2 carats in weight. The properties of green garnet stone from Africa are slightly different from stones from the Urals. African demantoids are often larger, but they are usually inferior to the Ural ones in beauty, and their color is rarely bright green. Stone care Jewelry with demantoid requires careful and careful handling. Wearing them constantly is not recommended. The gem should not be exposed to chemicals: detergents, cosmetics, perfume. It is not difficult to care for stone at home. To clean and remove dirt and dust, wipe with a soapy solution followed by removing moisture with a felt cloth or paper napkin. Jewelry is stored in a separate box, where it will be hidden from sunlight. How to distinguish from fakes Demantoid garnet is a rare and expensive mineral, so its fakes are common. Instead of gems, unscrupulous sellers try to sell glass or green cubic zirconia. Tourmalines are often used as a replacement. The easiest way to determine the authenticity of a mineral is to use a Chelsea filter. The glass will retain a green color, and the natural stone, when viewed through the device, will acquire a red tint.

Place of Birth

The most valuable demantoids, which have become classics, are mined in Russia, in the Urals. Three main Ural deposits can be distinguished: Karkodinskoye, Poldnevskoye and placers of the Bobrovskoye deposit. Green andradite was also found in the 1940s in Armenia and Azerbaijan, in the 1970s in Chukotka, Kamchatka and Sakhalin, and in the 1980s in the Polar Urals. But most of the samples found there cannot be classified as cutting quality. In addition to the Urals, jewelry-quality demantoids enter the world market mainly from only two sources: from Namibia (since the mid-1990s) and Madagascar (since 2008). Demantoids are also found in small quantities in Iran, Pakistan and Italy. Note that horsetail inclusions, previously considered characteristic only of Ural demantoids, were also found, for example, in demantoids from Pakistan, Iran and Italy. Therefore, to classify a demantoid as a “brand” Ural, some gemological laboratories pay attention not only to inclusions, but also to microimpurities. By the way, demantoids from Namibia and Madagascar, which occupy a significant part of the market, do not contain ponytails.

CHARACTERISTICS

The name of the stone can be translated as “diamond-like.” The comparison with diamond is not accidental. This is due to the fact that the properties of the stone are unique: the play of color flashes in faceted demantoid is even more pronounced than in diamonds, since the dispersion value of a demantoid (0,057) is higher than that of a diamond (0,042). Good properties also include the diamond shine and high hardness of this garnet. Mineral type: garnet, andradite variety Chemical formula: Ca 3 Fe 2 (SiO 4 ) 3 Optical character: isotropic Cleavage: very imperfect Density: 3,84 (±0,03) g/cm 3 Luster: glassy to diamond Refractive index: 1,888 (+0,007, -0,033) Color: yellow-green, green

INTERESTING FACTS

  • As the color saturation of the mineral increases, the manifestation of its dispersion in the form of a “game” of color flashes decreases.
  • Previously considered to be characteristic only of Ural demantoids, inclusions of the “horsetail” type were also found, for example, in demantoids from Pakistan, Iran and Italy.
  • The cost of the best demantoid from the Urals on the world market can exceed 10 US dollars per 000 carat.
  • Natural demantoids are small in size. Stones with processing and cutting rarely have a size larger than 5 mm. Crystals exceeding 1 cm in diameter are considered gigantic. During the mining of the gem, the largest finds are considered to be specimens of 149 and 252,5 carats. One of the famous stones, “Alexandrov’s Demantoid,” weighs 63 carats.
  • At the beginning of the 20th century, the “Ural emerald” was held in special esteem by Carl Faberge, who used it for his works. Rings with the mineral are present in the collection of the famous jeweler Tiffany.
  • Processing of demantoid stones is carried out in a similar way to diamonds – diamond cutting allows you to fully reveal all the beauty and charm of the stone.

History

Demantoid was first found in the mid-19th century in Russia. He was accidentally discovered by children on the Bobrovka River in the Urals. The find was then mistaken for an unusual chrysolite. “Ural chrysolite” began to be mined along the way by prospectors engaged in gold and platinum mining in the Bobrovka valley. When the Finnish mineralogist Nils Nordenskjöld came to Nizhny Tagil in 1849, he was shown the samples found. Nordenskiöld’s research showed that the mineral is not chrysolite, but a chromium-containing variety of andradite garnet with an unusual color from peridot to emerald. In 1854, he presented the results of his research at a meeting of the Imperial Mineralogical Society, and proposed the name “demantoid” for this stone in honor of its strong diamond-like “game”. The World Exhibition held in Paris in 1889 contributed to the growing popularity of the mineral. After it, the stone finally conquered both amateurs and professionals. Among the lovers of the gem were Emperor Nicholas II and the English King Edward VII.

Ennobling

Jewelry varieties of garnet usually do not undergo any types of refining. But this stone can sometimes be subjected to low-temperature heat treatment to remove the brownish tint and “reveal” a greener color, or to lighten the stone slightly. The elimination of the brownish tint in demantoids during heat treatment is associated with a change in the valence of iron. Heat treatment is common for Ural specimens, but there is no exact information on stones from Namibia and Madagascar. Demantoids of the Poldnevskoe deposit can be either heated or unheated. Stone from Bobrovka (Nizhny Tagil) is always without heat treatment, their color does not contain a brown tint. Specimens from the Karkodinskoe deposit are always heat treated; for them this is a standard and necessary procedure. Few gemological laboratories in the world indicate the fact of heat treatment in expert opinions. Many foreign market participants began to learn that this stone can be heated to improve color only recently.

The healing properties of the stone

According to lithotherapists, green pomegranate has healing powers and the ability to have a broad effect on the body.

Healers use the stone to treat chronic diseases of the throat and respiratory tract. To do this, use jewelry that is in contact with the desired part of the body: pendants, necklaces.

To restore vision, you need to look at the gem daily for about 2-3 minutes.

The mineral allows you to get rid of skin ailments, improve complexion and skin condition. Wearing a crystal near the heart will normalize the functioning of the cardiovascular system and normalize blood pressure.

Lithotherapists use gems to relieve nervousness, solve sleep problems, and reduce fatigue. Traditional healers use the mineral to treat infertility, recommending choosing jewelry in the form of a bracelet inlaid with green garnet.

Demantoid is a transparent variety of the andradite mineral of the garnet group of a green or yellow-greenish hue. Other names for the mineral: Ural chrysolite, green garnet stone, marvelite and tausonite.

The main physical properties of this stone are:

  • density – 3,89;
  • hardness – 6,5 (one of the softest stones of the andradite garnet variety);
  • variance – 0,57.

As for the color scheme, demantoid can be any shade of green. Sometimes there are pebbles with pistachio, brownish and yellow tints. Jewelers prefer to work with green samples, which are visually similar to emerald. The stone may contain iron, titanium particles and chromium.

Among the rare colors, one can highlight a red-violet hue, which looks unusual and attracts attention. There are lilac-colored stones with delicate tints and yellow-peach ones. Instances of such unusual shades can be found very rarely; generally, Ural chrysolite has a deep, rich green color and visually resembles a diamond.

Initially, the mining of these stones was carried out only in Russia, mainly in the Urals, and later in Kamchatka and Chukotka. At the end of the 20th century, green garnet began to be mined in Namibia, and in the 21st century, deposits of the stone were discovered in Madagascar. Currently, mining is carried out in Turkey, Iran, Switzerland, the United States and Sri Lanka. Deposits of green garnet are extremely rare in Italy. Most of them were found in Russia.

The cost of Ural chrysolite is significantly reduced by its fragility. Despite this, green garnet at the end of the 19th century was considered one of the most sold stones abroad. In nature, minerals are found in small sizes, round or oval in shape. Large gems are found in exceptional cases.

Among the varieties of garnet, demantoid is considered one of the most valuable, attractive and expensive stones. It has an extraordinary diamond shine. These stones are offered for sale quite rarely, and their value continues to increase.

Green garnets are highly processed and are often diamond cut. Due to the high degree of refraction, such processing can give the demantoid an incredible play of light, superior even to diamond. Pebbles play with almost the entire rainbow palette, unlike a diamond, which shimmers with only 3-4 colors.

Healing and magical properties

Some doctors claim that demantoid has healing properties when combined with certain metals. For example, men suffering from impotence can wear a gold ring with a green garnet on the middle finger of their left hand. It is advisable for people with high blood pressure or vascular diseases to wear beads with demantoid.

For women who have not been able to get pregnant for a long time, experts advise wearing a green garnet bracelet in a silver frame. If a person is bothered by a sore throat, or suffers from a disease of the respiratory system, then it is advisable for him to wear a pendant with demantoid. The green color of this stone has a calming effect on the nervous system, so it is recommended to be worn by people experiencing severe stress and a constant feeling of fatigue.

Jewelry made from this type of pomegranate can relieve a person from various skin ailments. It is enough that the product is located as close as possible to the source of the disease.

In addition to healing properties, the demantoid stone also has magical properties; it can make its owner successful, collected, focused and purposeful, brings success in his career and promotes rapid advancement up the career ladder.

Representatives of the fair sex who possess such a rare stone are happy in their personal lives. The chosen ones experience sincere feelings for them, and the marriage becomes strong.

For men, green pomegranate brings success in financial matters and helps them choose a suitable position that will bring a stable income. Demantoid will help you find true love and a faithful life partner, and will make a man attractive in the eyes of other women.

Green pomegranate can also be used as a talisman. It helps a person get rid of laziness, absent-mindedness, and protect envious people from the bad thoughts.

Astrologers advise using this stone for people born under the zodiac signs of Libra, Aquarius and Gemini. It is not advisable for Pisces to wear demantoid, as it will only bring misfortune and problems.

Green Garnet Jewelry

Since demantoids are popular among jewelers, expensive jewelry is made from it. Specimens with beautiful shades over 2 carats cost around $1 per carat. Stones weighing less than 000 carats cost $2 less.

Ural gems are considered one of the most expensive. Such stones have a rich, deep green hue and are not found anywhere else on the planet. Their distinctive feature is considered to be interspersed with asbestos in the form of a horse’s tail or sparkles of a golden hue, representing a tiger’s eye. These exceptional features can be seen under a microscope.

You should be careful when purchasing jewelry with this extraordinary gem, since scammers, trying to enhance the shade of pale stones, carry out heat treatment. The brightness of the stone, acquired in this artificial way, quickly disappears, and the procedure affects the color of the demantoid and makes it dull. Over time, after such manipulations, the stone completely loses its attractive natural shade.

It is advisable for people who want to emphasize their status to wear jewelry with demantoid. Rings with small stones look much more attractive in natural light. You can put on jewelry before going to important negotiations to attract good luck.

Demantoid earrings will perfectly complement your evening look. They can be worn to a special event. It is better not to combine jewelry with chrysolites with everyday items, but to wear them exclusively with formal or luxurious outfits.

As for other jewelry, green garnet pairs best with diamonds or sapphires. For example, a gold necklace with such stones will perfectly highlight an evening look.

Jewelry Care

If over time the demantoid begins to fade, then it must be washed under cool running water, adding a little soap solution, and gently wiped with a soft cloth.

It is recommended to store products with demantoid in a separate box, without placing it with other jewelry. Before you start cleaning the house, it is better to remove the green garnet ring to avoid interaction of the jewelry with chemicals, which have an extremely negative effect on the fragile mineral.

It is not advisable to keep the stone in direct sunlight for a long time. The gem shimmers beautifully in the sun, but ultraviolet rays negatively affect it, destroying the structure.

A product with demantoid should not be worn every day, since everyday household chores affect the quality of the stone over time. It is best to wear jewelry with this gem for special occasions.

How to distinguish an original demantoid from a fake?

A distinctive feature of the demantoid is the presence in the middle of a peculiar bundle of fibers in the form of a horse’s tail, and in a real Ural stone several such bundles may be present at once. Minerals from other countries may not have such bundles, but they are much cheaper.

There is another way to check the authenticity of a mineral: just expose the stone to the sun and see if it plays with all the colors of the rainbow.
