Alexandrite is the rare color change variety of the mineral chrysoberyl. Chrysoberyl can also form with microscopic tube-like natural inclusions that create a chatoyant effect when light shines on it. When chatoyant chysoberyl is properly oriented and cut into cabochon gemstones with a rounded upper surface, this chatoyancy is visible as a bright line passing back and forth over the surface of the gem, and it is popularly known as cats eye chrysoberyl. When a cats eye chrysoberyl gem also shows a natural color change from green under daylight to reddish hues under incandescent light, then it is known as a cats eye alexandrite gemstone.

Alexandrite is a very rare color-change variety of the mineral known as chrysoberyl. Transparent alexandrite is more than 1000 times more rare than transparent diamond! There are very few locations that produce alexandrite of commercial importance. Most of our alexandrite mineral specimens & crystals were mined in Bahia, Brazil where a deposit of alexandrite in schist matrix was discovered in the 1970's. Most of these Bahian raw alexandrite specimens are not gem grade, although alexandrite crystals with small transparent areas are sometimes found there. A significant deposit of gem-grade alexandrite was later discovered in Brazil in Minas Gerais in 1988. Be sure to see our Real Alexandrite Necklaces & Pendants, each one handcrafted from a gem-grade natural alexandrite crystal!
