Thanks to its wide range of colors, quartz occupies a large niche in the jewelry market.

​

RG Crystals has been engaged in production of synthetic quartz for 20 years, and our experts constantly strive to improve employed technology. Currently, we can offer more than 20 colors that reflect the natural quartz palette and more than 10 colors, which are not found in nature, and, therefore, are even of greater interest for sophisticated buyers.

​

In nature, amethysts are rarer than colorless, citrine and smoky quartz varieties. A clean and large crystal of dark amethyst is even more difficult to find due to depletion of natural deposits. Amethyst, which is manufactured by RG Crystals, has a magnificent violet color with a noticeable reddish hint. Such a hint is only typical for the most expensive natural amethyst, which is very popular in the market and obtained from certain Brazilian deposits.

​

RG Crystals experts have also made considerable progress in citrine production. We are pleased to offer not only such common colors as gold and lemon yellow citrine, but also saturated orange, honey and even red-yellow (Madera) colors that are rarely found in nature.

​

Our experts were also able to reproduce complex ametrine. This stone's name indicates the dual nature of the mineral that combines the properties of amethyst and citrine. Thanks to its unusual two-tone color, this variety of quartz has become increasingly popular in the global jewelry market.

​

Advanced synthesis technology enables us to obtain quartz of almost any preferred color and density. Color transition is also possible. We grow a milky-white, milky-green and milky-blue, and even a blue quartz, which has no analogue in nature.
