    Product Description for Min 4.75ct 11x11mm Trillion Russian Lab Alexandrite

    Alexandrite 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.

    "excellent stone. mine weighs out at 6.7 ct. and measures a little more than 11x11. the cut really makes the stone sparkle. i have other lab alex but none have quite the same twinkle in them. love it for my collection. i am thinking of making into a pendant or ring if i can find the "just right" setting. thanks jtv."

    Alexandrite is a highly prized variety of chrysoberyl. Alexandrite only forms when aluminum/beryllium and chrome (which rarely occurs in nature) come together, accounting for its rarity. On Mohs’ scale of hardness, alexandrite is 8.5. It has a strong vitreous luster and primary sources include Sri Lanka, Zimbabwe, and Brazil (Minas Gerais).


    Color

    Alexandrite is typically found in blue, blue-green, and brownish-green shades. However, this phenomenal gem is known as "emerald by day, ruby by night" because of its ability to change color, depending on the type of light in which it's viewed. In the daylight and fluorescent light, alexandrite appears in shades of blue and green, but in tungsten (incandescent) light, it appears in shades of red. Other alexandrite color changes are possible (from blue to purple, from greenish blue to reddish blue, from brownish-green to brownish-red, etc.) and also highly prized.
