Alexandrite is the rare, phenomenal, color-change variety of the chrysoberyl mineral, along with its cousins yellowish transparent chrysoberyl and chatoyant or cat's-eye chrysoberyl. The unlikelihood of the rare element chromium being in the right place to combine with aluminum and beryllium under exactly the right conditions to create alexandrite is what makes it so rare and valuable.

Alexandrite Gem Stone.
In the lab certificate trhe colour of the stone is shown as bluish but in reality the stone is pink in colour.The stone is not changing its colour. The piece of gem stone sent to me appears to be a piece of glass. i hvave serious doubt whether it is original Alexandrite stone or not. I think that i have been duped and I have lost money.
