Russian Brilliants® is a laboratory-grown stone that is classified as a diamond simulant. A simulated diamond simulates or imitates the appearance of a mined diamond, but does not duplicate the characteristic chemical and physical properties of the natural gemstone. While Russian Brilliants® simulated diamonds do an excellent job of duplicating the appearance of a mined diamond, they are not the same thing as a mined diamond. This applies to all simulated diamonds on the market today including all of our online competitors.

Russian Brilliants has it's origin in a synthetic material first developed by the French in the 1960’s and later perfected by the Russian's in 1973 for use as an optical material in their space program. This early material, synthetic zirconium dioxide, was the original cubic zirconia. Over the last 40 years there have been many advances in the chemical and optical quality of this man made material. We are the exclusive distributors of Russian Brilliants which we believe is the most natural looking diamond simulant available today. We select only the finest quality rough material available. And every stone is hand cut and faceted to ideal proportions to most accurately replicate the look of a fine quality mined diamond. A one carat Russian Brilliants stone with its brilliance and fire is visually equivalent to the world's finest DE color VVS clarity diamond valued at $17,000.

Many people don't realize that if you are overly rough with a mined diamond you can chip or even break it. That being said, a mined diamond set in a ring or other jewelry will not show the signs of normal daily wear over time such as minor abrasions or scratches. Anything that's not a diamond, whether it's a sapphire, ruby, emerald, blue topaz, amethyst, or any semi-precious or simulated diamond material, will be susceptible to some scratching, chipping or minor abrasions over time as a result of daily wear. It all depends on your lifestyle and what you do with your hands throughout the day. Russian Brilliants simulated diamonds come with a lifetime warranty that covers damage of any kind, for any reason.

Russian Brilliants are guaranteed never to fade or discolor internally. Some other simulants have internal microscopic pinpoint inclusions that implode when exposed to sunlight, leaving the stone looking cloudy and discolored. Our stones are completely stable in sunlight so you’ll never have this problem. Guaranteed.

Don't be fooled by this old sales pitch. Almost all gemstones common in fine jewelry will cut glass. Why? Diamond is a 10 on the mohs hardness scale. Glass has a mohs hardness of only 6.5. Since most gemstones used in jewelry (i.e., sapphire, ruby, topaz, quartz, citrine, amethyst) have a hardness above 6.5 they will all cut glass. And yes, almost all simulated diamonds including Russian Brilliants will cut glass.

Russian Brilliants are hand cut, faceted and polished to most accurately replicate the look of a fine quality mined diamond. Russian Brilliants were the first fine simulated diamond offered online and are still the best simulated diamond available. For more information read our Compare Russian Brilliants page.

We have heard many stories from our customers about showing their rings to another jeweler who was impressed with the quality of their "diamond", and we work with many expert jewelers who recommend Russian Brilliants to their customers.

Newer electronic diamond testers can distinguish between diamond, moissanite and cubic zirconia. These devices measure the electrical conductivity of a stone. Since mined diamonds, Moissanite and other simulated diamonds are all made of different material, they will all have different measures of electrical conductivity. Only a real diamond will test positive with an electric diamond tester. Most importantly, the brilliance and beauty of a stone cannot be measured by one of these devices. We’re so confident you’ll be impressed by our simulated diamonds, we invite you to take our Russian Brilliants Challenge and preview one of our stones yourself, risk free.
