Shanghai Chinese Crystal Manufacturing Co.,Ltd

Our created gemstones are chemically identical to gemstones mined naturally.

Lab created alexandrite gemstones are amazing gemstones for jewelry, because faceted gems undergo a dramatic color change in different types of light. In warm indoor incandescent or candle lighting, this gem is a rich purplish red color. In bright daylight, it is greenish blue. The man-made alexandrite grown or created in our lab, such as natural alexandrite, is a member of the chrysoberyl family which has the chemical composition beryllium aluminum oxide.

Be cautious when buying lab alexandrite, because many dealers indiscriminately use the term for imitations (such as color-change corundum). Chrysoberyl occurs in a range of colors including green, yellow, and brown, and often exhibits a cat's eye chatoyancy. The name alexandrite is reserved for the very rare and valuable color-change variety of chrysoberyl. The best natural chrysoberyl, including alexandrite, has been found in the Ural Mountains of Russia. In fact, the color-change variety is named after Prince Alexander of Russia because it was discovered in 1830 on the day of his coming of age. Natural alexandrite is so rare that few people have ever seen one, and its value is on a par with emeralds, rubies, and sapphires. The alexandrite gemstones created in our lab have higher perfection than is usually seen in natural stones. We are able to offer them at a small fraction of the cost of comparable natural stones. Alexandrite is the birthstone for the month of June and the gemstone for the 45th and the 55th wedding anniversary.
