About Alexandrite

Alexandrite is one of the rarest of all colored gemstones and is famed for its color change from green in daylight to red under incandescent light. Fine faceted alexandrite over 1 carat is more valuable than sapphire, ruby or emerald.

Alexandrite is a variety of chrysoberyl, with an excellent hardness of 8.5 on the Mohs scale, placing it right behind sapphire and ruby. Alexandrite is rare because of its chemical composition. Chrysoberyl is colored by traces iron and titanium, but alexandrite is also colored by chromium, which gives it the emerald green hue in daylight.

I purchased several green chrome tourmaline loose stones from GemSelect Twice over the last 2 years. Those stones made my wife' wedding ring, necklace and earings. Created by the goldsmith at Maus jewelers. . . Masterpieces of God's creation and mans creativity to the glory of God's love! they couldn't have done it without starting here first! FANTASTIC!!!
