artificial gems

1. Thanks to the special surface structure, there are no greasy fingerprints left on the stone, but the diamond quickly loses in the play of light.
2. Stones (jewelry inserts) are cut according to the laws of optical science, but diamonds, due to their high cost and for the sake of preserving carats, are cut taking into account the preservation of the maximum size, possibly with damage to optical symmetry.
3. The heat resistance of moissanite is 1000 degrees higher than that of diamond.

And the disadvantages of moissanite stone.

Unlike a diamond, a moissanite stone has birefringence and if you look at it off the optical axis, you will notice a bifurcation of the back edges. Therefore, when cutting, this property is taken into account and the moissanite is oriented in the product so that this effect does not appear.

Moissanite production and marketing

Well-known company Charles & Colvard is based in North Carolina (USA) and produces moissanite (moissanite analogue of diamond, artificially grown) and jewelry with them. Through the introduction of modern technologies and strong marketing, the company has been leading the global market since 1995. The Internet did not go unnoticed, the trading platform – moissanite.com is implemented as a 100% subsidiary of Charles & Colvard and carries the same tasks – marketing and sales. Given its weight in the global marketplace, Charles & Colvard actively influences jewelry industry trends as a member of several well-known and respected associations and organizations promoting ethical trade, business ethics, education and consumer trust.

Moissanite price per carat

The price of moissanite depends on its size, color, cut, color, etc. We offer gem-cut and white stones, so basically the cost of moissanite depends only on the size. We indicate the size of stones in mm, but if you are interested in the size in carats (moissanite price per carat), see the conversion table:

Jewelry corundum is a natural gem, varieties of which are the usual ruby ​​and sapphire. There are synthetic analogues of the stone, but they are not very expensive, although their physical and technical properties are close to the original. The gem is mined in many countries around the world. And the final physical and technical properties are obtained after thermal or chemical treatment.

Varieties of precious mineral

To understand what corundum is in jewelry, it is worth understanding which gems belong to this group of minerals. Moreover, the pure mineral is increasingly called oriental diamond, violet, adamas and even soymonite.
Pure corundum has almost perfect transparency. It has a bright glass shimmer that makes it look like a diamond. Jewelers distinguish the following types of gems from this group:
– ruby ​​has a red, pink or transparent color and contains chromium additives;
– sapphire with a blue or transparent tint contains titanium impurities;
– padparadscha or oriental topaz has a yellow, orange, transparent tint, contains alloying components in the form of iron and nickel;
– white crystalline alumina;
– oriental amethyst or oriental amethyst with a purple tint;
– Oriental emerald or oriental emerald has a green or transparent color.

The cost of natural corundum depends on its color and transparency. Often, for one clean copy without defects and inclusions, they pay 400 US dollars on jewelry markets around the world. The cost of 1 g with minor defects varies within $90.

Features, physical and chemical properties, places of mineral extraction

Corundum jewelry stone is mined in India, Sri Lanka, Madagascar, the USA, Canada, Norway, the Russian Federation (Chelyabinsk region, the Urals and North Karelia). The gem in the natural environment is formed by the contact of limestone, dolomite and granite. By origin, the stone is associated with igneous rocks and is natural aluminum oxide. Approximately 50% of the stone’s composition is violet.
The physical and chemical properties of the precious gem are as follows:
– strength on the Mohs scale – from 8,5 points;
– density per 1 cm³ – about 4 grams;
– trigonal system and lack of cleavage – high purity;
– crystalline structure – when a ray of light is directed at a mineral, it is refracted into many rays;
– glass diamond luster;
– resistance to high temperatures – melts at 2050 ⁰С;
– resistance to chemical and mechanical influences.

The synthetic analogue is often used in jewelry. It is similar in properties to the original. But it is not distinguished by its high price and durability. The first version of synthetic corundum was obtained in 1892, when scientists created a “fake” ruby.

Specifics of an artificially created mineral

Wondering what synthetic corundum is and is it used in jewelry? An artificially grown gem is distinguished by its external beauty, but by reduced strength and transparency. The natural original always costs more and is installed only in gold or silver products.
At the same time, in jewelry and inexpensive silver products, synthetic corundum is used, created by one of the following methods:
– hydrothermal method;
– Czochralski technique;
– option of zone melting;
– dissolution of the alloy in a special melt;
– obtaining a gem from a gaseous environment.

Each method has unique features and technologies. The result is synthetic corundum, different in color and physical and technical properties. Some artificial options have a shade that does not exist in nature at all.

Synthetic mineral palette

As a result of “growing” corundum, stones of the following colors are obtained:
– a transparent stone was previously used as an imitation of a diamond, then cubic zirconia began to be used instead of precious gems;
– orange artificial stone is used as a “substitute” for sapphire (subtype padparadscha and hessonite); often it replaces natural hyacinth;
– red synthetic gem – imitation of natural ruby, spinel and garnet;
– the yellow version is used in jewelry as artificial topaz or heliodor;
– dark red corundum – used in jewelry instead of almandine or pyrope;
– green – imitation of demantoid, emerald, chlorosapphire and chrysoberyl;
– a pink stone, created synthetically, imitates topaz, beryl, pinkish sapphire and tourmaline.

The cost of a synthetic “substitute” is much lower than the original. To distinguish it from natural corundum in jewelry, just read the tag carefully. It is on it that the method of processing a real gem and its weight in the carat measurement system are indicated.

Is it possible to identify natural corundum at home?

Having understood the question of what natural and synthetic corundum is and how it is used in jewelry, it is worth understanding how the real version of the gem differs from its analogue. If you have been given a piece of emerald or sapphire, but you are not sure of the authenticity of the stone, check the gem in the following ways:
1. Real sapphire does not have a uniform uniform color. Upon closer inspection, it is easy to see the alternation of white and dark shades.
2. Natural rubies and sapphires often have inclusions of zircon crystals that can be seen under a magnifying glass.
3. Bubbles are only available in synthetic gems. It is worth considering that gaseous inclusions may occur in natural stones, but they have an ideal spherical shape.
4. The presence of some specific organic matter, unusual for diamonds and natural stones, indicates the synthetic origin of the mineral.

You can always take the gem for examination to special evaluation centers or to a jewelry pawnshop. It is there that they will quickly tell you how high-quality and expensive the corundum is in front of you.
