The rarest green diamond and its uniqueness: properties and famous specimens

A green diamond is a rare stone, more expensive than only diamonds of red shades. The cost of large specimens of rich color reaches several million dollars. Such jewelry is valued not only for its beauty. They are considered feminine stones that can prolong youth and protect pregnancy.

Description of green diamond

Natural green diamonds are a rare find. Not every jeweler, even one working in an international gemological laboratory, will see, much less hold, such a stone in his or her lifetime. They rank second in rarity after red diamonds.

In terms of physical and chemical characteristics, green diamonds are not much different from classic colorless diamonds. The main element in their composition is pure carbon. They have a cubic crystal lattice where the atoms are arranged very tightly. This gives such minerals increased hardness.

Green diamonds have the following properties:

• Unsurpassed hardness – 10/10 on the Mohs scale.
• The shine is diamond.
• Color – from a barely noticeable “greenish” to thick, saturated.
• Density – 3.55 g/cm3 (at equal volumes, 3.5 times heavier than water).
• Cleavage is perfect.
• Gives a conchoidal splinter fracture.
• Transparency – translucent, sometimes due to the thickness of the shade it becomes translucent.
• Fragile. Shatters when dropped or hit.

How to wear and care

Luxury stones deserve proper care and handling.

How to wear

Jewelry with precious stones of the first row is worn for evening status events, under a wardrobe of the same level. The green color scheme is pleasantly complemented by white or pink diamonds.

Diamond is fragile and can break if dropped.

When putting on jewelry, especially earrings, it is advisable not to touch the stone: your fingers will leave traces of grease and the gem will fade.

How to care

Although stones are rarely displayed, they do become dirty and require maintenance.

Every year, jewelry is taken to a jeweler for inspection. He will assess the condition of the frame and the gem, check the reliability of the fastenings, and carry out ultrasonic cleaning. Amateur activities such as using napkins and products for cleaning jewelry stones are excluded.

For each piece of jewelry, a safe box of the appropriate level of performance is allocated.

Causes of green color

Scientists continue to puzzle over how diamonds of different shades of green were formed in nature. The following factors are believed to have contributed to this:

• The influence of natural radiation. Green nuggets are often found in places where background radiation is high (near uranium deposits). The formation of such stones takes millions of years.
• The action of high temperatures and pressure, which led to a change in the crystal lattice of the mineral.
• Chromium inclusions entering the crystal. This happened at the stage of gem formation.

In order for a transparent diamond to acquire the shade of fresh grass, the following conditions are necessary:

• A certain amount of nitrogen in the composition. This component is found in all diamonds, but its content is not the same in samples of different colors. Green diamonds, in terms of the presence of this substance, occupy an intermediate position between yellow and black diamonds.
• Irradiation with thorium (uranium). If a stone is exposed to alpha particles, it acquires a superficial greenish tint, which disappears during the cutting process. Deep exposure to beta or gamma rays ensures lasting, uniform pigmentation and turns the mineral into an elite green diamond.

Artificial creation of color samples

High-quality green diamonds are so rare that they are known by comparison. Only one such stone is found per year and after cutting (which takes 6-8 months, or even 12) it is put up at auctions. For several centuries, these diamonds remained the privilege of a select few. Other people could admire the green “multi-carat” cars only in photos of celebrities and multi-billionaires.

Everything changed at the end of the last century, when the demand for fancy diamonds increased sharply. Scientists have developed technologies that make it possible to give colorless diamonds an arbitrary shade. Artificially “colored” minerals are 10 times cheaper than natural green diamonds that have not undergone additional color treatment.

To give diamonds a “grass” color, the following techniques are used:

• Irradiation (irradiation) is a cheap and safe method. The author of this technology is William Crookes, an English chemist and physicist. In 1904, he managed to color a diamond green in laboratory conditions by exposing it to radiation. However, this experiment cannot be called successful, because the mineral became a source of dangerous radiation. Currently, colorless diamonds are exposed to gamma rays, which are sent by a radioactive isotope of cobalt. As a result, the minerals acquire a uniform bluish-green hue. The disadvantage of the method is that the treated stone has to be kept in the laboratory for several months until its radioactive background decreases.
• Cyclotronation is an outdated technology. Diamonds are placed in sealed chambers (cyclotrons) and bombarded with deuterons and protons. This method has two significant drawbacks: the treatment produces zonal staining (some areas of the stone remain colorless). Plus, after “repainting” the diamond remains “phonic” for a long time.
• Exposure to neutrons and electrons is the most productive method. It provides uniform, permanent coloring to a depth of 1 mm. After “greening” the stone gives off intense white fluorescence.

All green diamonds, which are inlaid with jewelry from the assortment of ordinary jewelry stores, have undergone color modification.

Without special equipment, it is impossible to detect traces of processing. This can only be done by experts from a gemological laboratory.

If the color of the diamond does not match its natural color and has been changed by external influences, then the certificate accompanying the stone will be marked “treated.” In the expert opinion, a natural green diamond is designated by the word “natural”. Such samples are purchased to order for a specific buyer or sold at auctions at Sotheby's and Christie's.

Color intensity

Saturation and shades of color are one of the main criteria for assessing the quality of green diamonds. The brighter the stone, the higher its jewelry value and cost. According to the accepted classification, there are 27 shades of color and 9 gradations of intensity of fancy diamonds:

• pale colored, slight degree – Faint;
• very weak – Very Light;
• weak fantasy – Fancy Light;
• fantasy - Fancy;
• dark fantasy – Fancy Dark;
• intense – Fancy intense;
• intense fantasy – Fancy Deep;
• bright fantasy – Fancy vivid.

Diamonds with a deep, pure green color are valued the most. Such specimens are extremely rare. Among jewelers they are usually called “ultimate gems”. The price of diamond rarities starts from a million dollars. Somewhat more often you come across samples in which shades are mixed with the main color. This reduces the cost of the stone.

If a mineral fluoresces when exposed to ultraviolet light, its price is reduced by 30%.

The color palette of green diamonds includes the following shades:

• greenish;
• olive;
• green with a yellowish tint;
• grayish green;
• grayish yellow;
• bluish green;
• chameleon is a stone with an alexandrite effect (in the light it shimmers in shades from gray-blue to olive and yellow-green).

The standard for fancy diamonds of the “color of hope” is the Dresden Green Diamond. After cutting, the diamond weighed 41 carats. In the nugget its mass was twice as high. This is a bright, luxurious diamond with a natural apple green color. The crystal is expertly pear-cut and set into a ring.

The stone, named after the city of Dresden, has an interesting biography. It was discovered in the 18th century. in India. British merchant Marcus Moses brought a rare diamond to Europe. The mineral won the heart of King George I, but the Dutch merchant Dels bought a valuable sample.

Then the Saxon Duke Frederick Augustus II became the owner of the green “miracle”, and he spent the money that was intended to buy guns on its acquisition. Since then, the 40.70-carat diamond has settled in Germany. He left Dresden only once. After the Great Patriotic War, the stone was brought to the USSR, and in 1958 it was returned to Dresden.

The second “exemplary” green diamond is named Great Gruosi. The stone weighing 25 ct is named after the jeweler, “the king of black diamonds” – Fawaz Gruosi. This is a flawlessly clear crystal of a gorgeous bright green color.

Other sensations in the world of green diamonds:

• Lal Oyla (Lal Oyla) is a bright green diamond of 70 ct, located in the collection of Harry Winston.
• Yakut green is a dark green diamond, 61.18 ct before cutting, after processing it “thinned” to 18.01 ct.
• Green Diamond De Grisogono - the weight of the nugget was 100 ct, after cutting - 25.06 ct, inserted into a ring made of white gold and black diamonds. Price: $7.5 million.
• Green Diamond Ring – the stone weighs 2.52 ct, adorns a gold ring with a discreet design, was purchased for $3 million.
• Aurora Green is a rich green mineral weighing 5.03 ct, sold at Christie's for $16.8 million.

Application

Diamonds of all shades of green are considered valuable. Such rare gems are not used in the industrial sector. The areas of their use are limited to three areas:

• Collecting. Natural green diamonds and polished diamonds end up in private collections or become museum exhibits. Collectible items include “solitaires” over 1 ct, with a bright fancy color and purity close to perfect. Stones with an unusual “biography” are also of interest to collectors of precious minerals.
• Jewelry making. If a diamond is found that naturally has a green tint and high clarity, it is used to make luxury jewelry. The cut of such samples is carefully selected. The processing of the mineral is carried out by top-class specialists. This is painstaking and time-consuming work. After cutting, the weight of the stone can decrease by 2-3 times.
• Method of investing funds. Green diamonds are in second place in popularity and cost (among fancy diamonds) after red ones. The price of stones starts from $250 thousand. per carat, there is a tendency for the cost of these diamonds to increase. Even if the mineral has shades, it is a very profitable investment.

A carat of green-colored diamond costs much less – up to $25 thousand.

The price of products with modified crystal is also high, but this cannot be considered as a long-term investment. You will never sell them at auction for five zeros.

How to spot a fake

There is no problem for owners to identify top-class stones. They are purchased by order or at auctions at Christie's or Sotheby's.

The origin of each specimen is confirmed by a GIA (Gemological Institute of America) quality certificate. It contains information about the place of extraction, natural color and others.

Ennobled copies are also provided with certificates. It is impossible to identify them at home, only with special equipment.

Medicinal properties

Among all natural minerals, diamonds are considered the most powerful healers. They have a beneficial effect on the immune system, calm the nerves, relieve insomnia, and reduce the likelihood of infectious infection.

But green diamonds also have a number of specific medicinal properties:

• prevent sclerosis;
• reduce the risk of apoplexy;
• serve for the prevention of urolithiasis;
• get out of depression;
• treat migraine;
• accelerate wound healing;
• increase visual acuity, protect against the development of eye diseases;
• slow down aging;
• help a woman bear and give birth to a healthy baby.

Unlike clear and black diamonds, green diamonds are healthier for women than for men. They have long been considered “maternal”. Girls of any age can wear jewelry with such stones. This will have a positive effect on the reproductive sphere and will help preserve youth and beauty for a long time.

Main conclusions

1. A natural green diamond is one of the rarest stones. The Dresden Green Diamond, whose history dates back to 1741, is considered the standard.
2. Diamonds to obtain unique gems are mined in South America, as well as in Australia.
3. The stone is credited with pronounced magical and healing properties. It is ideal for Aries, Sagittarius and Leo, as it helps to develop the best qualities of character. Representatives of other zodiac signs can also wear jewelry with rare diamonds. But it will not exhibit magical properties.
4. Used in the jewelry industry and investing.
5. The price of 1 carat depends on the origin of the mineral. Specimens grown under artificial conditions are tens of times cheaper than those obtained from natural diamonds. The buyer of a synthetic diamond must be informed of the origin of the stone by the seller.
6. At home, it is impossible to distinguish a green diamond from a copy. The examination is carried out by an experienced gemologist using special equipment.

What You Should Know When Buying Green Diamonds

Apple green diamond jewelry is expensive. To avoid purchasing a fake, refined or artificially colored mineral for an immodest sum, use the following recommendations:

• Buy jewelry with fancy diamonds in large jewelry stores with a proven reputation.
• When purchasing, read the tag. It indicates the name of the stone, weight, size, clarity, and cut type.
• Each green diamond (including refined and artificially “colored”) is supplied with a certificate stating its origin and the technological modifications to which it has been subjected.

If your financial capabilities allow you to “take a swing” at buying a green diamond of natural origin, look for a suitable stone in one of the world’s diamond “capitals” - Hong Kong, Antwerp, Tel Aviv, Mumbai. Don't expect to find such an exclusive in Russia. No matter what the consultant says, 90% of colored diamonds offered by the domestic jewelry retail chain are modified.
