Product Description for Min 4.50ct 12x10mm Oval Russian Lab AlexandriteAlexandrite is a phenomenal gem known as "emerald by day, ruby by night" because it changes color from green in fluorescent and daylight to red in incandescent light. Ranking 8.5 on Mohs' scale, it's ideal for daily wear. Discovered in 1830 in emerald mines of Russia's Ural Mountains, it was named for Czar Alexander II. Found in Brazil, Sri Lanka, and Tanzania, alexandrite only forms when aluminum/beryllium and chrome (which rarely occurs in nature) come together, accounting for its rarity.

"This stone is beautiful. I louped it and saw no inclusions or feathering. And the color change is breathtaking. Russian lab alexandrites are one of the most striking gemstones I own. For the great prices at jtv, everyone can afford to have at least one of these magical gems in their collection."

"internet pictures don't do these gems justice! Russian Lab Alexandrite is one of the most captivating gems I've ever seen. It really "talks" to me. I just had to have it. To me it rivals tanzanite and paraiba. The deep, rich purple is breathtaking and the blue, too scrumptuos to mention. Thanks jewelry tv for introducing me to the wonderful world of gemstones!"
