How much does an artificial emerald cost?

The mining region is one of the most important factors. The fact is that the quality of an emerald is largely determined by the nature of its deposit. Almost all Colombian stones are clean, transparent, almost free of impurities, chips, cracks and other defects. In Zimbabwe, on the contrary, the vast majority of mined emeralds are cloudy and not so spectacular.

The most common emeralds include stones from Zambia, Africa. The deposit was discovered only in the early 2000s, but the nuggets found there have already amazed jewelers from all over the world with their quality and availability. Zambian emeralds are bright green and perfectly transparent. Today Zambia is the leader in the production of gem-quality emeralds.

The historic Malyshevsky mine in the Urals also produces some of the most valuable and expensive emeralds. The stones mined here are characterized by an incredibly rich color, bright grassy hue, transparency and a smooth surface without defects. The amount of impurities is minimal. In addition, the Malyshevsky mine often contains the rarest giant emeralds. Buying Malyshevsky emerald today is not easy, since this mine is a strategically important site for the country, and visits to it, as well as the purchase of raw materials, are very limited.

At the same time, absolutely pure and transparent emeralds are among the rarest. As a result, they may turn out to be even more expensive than diamonds, especially large stones weighing more than 5 carats. For such stones, the country of origin fades into the background, and color and clarity become the most important pricing parameters.

The type and quality of cut also determines the price of the stone. A small perfectly cut emerald can cost as much as a stone twice the size, but with an “economical” simple cut that retains the weight of the stone. The classic method is the emerald cut – it minimally grinds the crystal, keeping it large and massive. But there are also round and oval shapes. The pear-shaped cut – in the shape of a drop – is very popular.

Some complex cutting methods can also reveal the richness and depth of an emerald – and thereby increase its price.

Also, the color saturation determines the price of the stone. The rarest and most expensive are intense green, dark and deep. Light stones are cheaper. However, some bright grassy emeralds can compete with diamonds in price.

A certificate issued by a gemological laboratory is a document confirming the authenticity and characteristics of the stone. Essentially, it increases customer confidence. The most reputable laboratories and certification centers are located in the centers of extraction, cutting and sale of precious stones. In the USA it is GIA. In Russia – Gemological Center of Moscow State University. M. V. Lomonosov. Switzerland: Gubelin, SSEF, GRS. Sri Lanka: EGL, GIC, GGTL. Thailand: AIGS, Lotus Gemology, GIT. Well, international IGI.

Finally, natural emeralds are several times more expensive than artificial ones. The latter are often cheaper even than semi-precious stones.

There are several classification systems for emeralds. In Russia and many post-Soviet countries, a set of standards is used that distinguishes five groups of gems by color:

  1. Dark green.
  2. Medium dark green.
  3. Medium green.
  4. Medium light green.
  5. Light green.

Emeralds from the first color group are the most expensive, and from the fifth – the cheapest (except when they have ideal purity and transparency).

To assess purity, a system of three categories is used:

  1. Transparent, practically free of impurities and inclusions.
  2. Transparent, with a small amount of impurities and inclusions.
  3. Stones with a large number of defects – impurities, opacities, cracks.

Stones of the first category are the most expensive.

The classification system also distinguishes four gradations of mass:

  1. Small – having a mass of 0,49 carats or less.
  2. Medium – having a mass of 0,5–1 carat.
  3. Large – weighing 1–10 carats.
  4. Very large – having 10 carats or more.

Categories are arranged in order of increasing cost: small – the cheapest, very large – the most expensive due to their rarity.

Matching the size and weight of emeralds

The size (width and height) of the stone depends on the weight of the raw material and the future cut. It is impossible to cut the same pair without large losses. Stones are selected for pairing after the raw material has been cut, since first of all they try to preserve the total mass of the emerald. A cut emerald may be flat or, conversely, too deep. Therefore, two emeralds of the same weight can have different sizes. Well-sized, ideally cut stones will always cost more.

It may happen that after applying a classic cut with facets, the emerald will lose its attractiveness, since the facets will be emphasized and show inclusions that will be perceived as flaws in the stone. To avoid this, the emerald is cut into a cabochon cut. The cabochon has no edges; it is flat on one side and convex on the other.

How emeralds are imitated and counterfeited

The high price and impressive demand for emeralds encourage unscrupulous jewelers to counterfeit these precious stones. However, the methods of misleading may be different. Sometimes semi-precious stones are sold under the guise of emerald, and sometimes emeralds of laboratory origin are sold under the guise of natural ones.

Imitations of emeralds (semi-precious stones)

Semi-precious stones are often sold under the guise of emeralds. They are also green, which can mislead an inexperienced buyer. At the same time, the list of semi-precious stones that can be sold under the guise of emeralds is quite extensive.

Demantoid – a rare bright green stone. Its pure and transparent varieties have excellent light refraction, so in some cases they can be even more expensive than emeralds. However, for falsification, of course, low-quality demantoids are used.

Fluorite rarely used in jewelry. This is a very soft stone that has a low shine and scratches quickly. But thanks to its rich green color, scammers use it as an imitation emerald.

Tourmaline It is usually red in color, but the variety found in Tanzania is an intense green. This stone is very similar to an emerald and can fool even a novice jeweler. However, an experienced specialist will instantly distinguish tourmaline from a gemstone, since it has a higher degree of light refraction.

Chrome diopside It is so similar to an emerald that it can deceive both buyers and jewelers. Fortunately, this stone is quite rare. It is possible to distinguish chrome diopside from emerald only in laboratory conditions. By the way, chrome diopside was previously mistakenly called “Siberian emerald.”

Glass also often used in counterfeiting gemstones. And not only emeralds.

Chrysolite – a semi-precious stone that is often tried to be sold under the guise of an emerald. But an experienced jeweler can easily distinguish these nuggets. Peridot is characterized by high birefringence – if you look at it through a magnifying glass or microscope, you can easily see the birefringence of its faces. Also, inclusions in chrysolites differ from inclusions in emeralds.

Uvarovite often found in the form of a “brush” – a group of small crystals on one base. Therefore, they sometimes try to pass it off as a druse – this is a nugget that consists of a group of emerald crystals fused on one base, they are called a “druze”. Such specimens are not cut, but sent to collections in their original condition. Their cost significantly exceeds the cost of faceted emeralds.

Jade has a characteristic “greasy” sheen.

Kyanite, synthetic quartz, YAG, green spinel and moldavite can also be used as imitation.

Artificial emeralds began to be produced in the first half of the 20th century. To grow them, the conditions that are observed deep in the earth’s crust are recreated. In laboratory settings, emeralds are “born” in just a couple of months.

The chemical composition of natural and laboratory-grown emeralds is identical. However, there are still differences in the stones. While natural emeralds without inclusions, defects and impurities are extremely rare, each specimen grown in a laboratory is perfectly pure. Therefore, gemologists, having encountered a stone devoid of “flaws,” conduct complex analyzes to verify its natural origin.

In order for artificial emeralds to be as similar to natural ones as possible, they can be processed – cracked, or specially grown with gas bubbles and inclusions. For an experienced gemologist, it will not be difficult to distinguish such a stone from a natural emerald, although magnification greater than that of a simple magnifying glass may be required.

Although artificial emeralds may seem even more beautiful to some than natural ones, they lack individuality and their own history. And most importantly, they have no investment value. Over time, such stones only become cheaper.

Doublets and triplets

Doublets and triplets are one of the crudest methods of counterfeiting emeralds, intended exclusively for inexperienced buyers. To counterfeit a gemstone, two pieces of the mineral are glued together to form a doublet. If you need to make a triplet, use three pieces.

Cubic zirconia, glass and other materials are used to create doublets and triplets.

In some cases, real natural emeralds, sometimes clear varieties of beryl, are used to create the doublet and triplet. Usually these are small, damaged stones that cannot be cut. The main problem of such doublets is the low quality of gluing; such an “emerald” simply collapses over time.

The result is cheap “stones”. If they are trying to sell you an “emerald” at a suspiciously low price, you should not rush into the purchase.

Luxurious jewelry with natural emeralds

Jewelry with emeralds is not only a luxurious decoration, but also a good investment. Therefore, you need to approach your purchase responsibly. In our catalog you will find proven jewelry with emeralds – with natural stones of exclusively jewelry quality.

Not every professional jeweler will be able to distinguish a natural emerald from a hydrothermal emerald grown in a few weeks in a laboratory. Hydrothermal emerald is more durable and, like natural stone, is resistant to sunlight and heat.

Nowadays, people have learned to control the growth of emerald, and influence not only its size, but also its quality. Such hydrothermal stones ideally complement jewelry made from classic red gold, and their cost is significantly lower than that of emeralds, which have matured in the earth’s crust for thousands of years.

Synthetic gems are created as follows:

  1. The powder remaining after cutting a real nugget is placed in an autoclave along with other components (chromium, beryllium oxide, silica and aluminum oxide).
  2. Next, chemical reactions occur in the vessel under high pressure and temperatures.
  3. The autoclave is then placed in a special zone where the crystallization process takes place.

A finished hydrothermal emerald can be obtained approximately a month after the start of its creation; nature has been working on this for many thousands, or even millions, of years.
