media type="file" key="26.mp3" width="240" height="20" Alexandrite is my birthstone and it is very interesting .Alexandrite is named from the past Czar of Russia. Alexandrite can cost $780.00-1200.00$. Alexandrite is also called Chrysoberyl. A cat's eye is an Alexandrite that has been polished. It was discovered in April 1834 in the emerald mines near the Tokoraya River. On the hardness scale of 1 to 10 it is an eight and a half. That means it's a pretty hard mineral. I feel pretty lucky to have such an interesting birthstone. __Comments from Teachers during the research process:__
