Chrysoberyl was very popular in Victorian and Edwardian times, when it was often inaccurately referred to as Chrysolite.
Chrysoberyl's have long been considered a good luck charm in numerous cultures.
Chrysoberyl's are known to be associated with discipline and self-control. They are said to promote concentration and the ability to learn and to help the wearer with striving for excellence. In addition to this, they bring peace of mind, clearer thinking, and increased self-confidence helping one become more understanding of the fact that they have everything they already need to succeed.

The original source of Alexandrite in the Ural Mountains of Russia has long since dried up. Today they have been re-opened, but only produce a few carats each year. Today Brazil and Sri Lanka (Ceylon), are the two major producers of the stone. However it is also found in Myanmar (Burma), India, Madagascar, Tanzania, and Zimbabwe. Unfortunately, none of these locations produce as rich and vivid colors as the original gemstones mined in Russia.
Deposits of Cat's Eye can be found in Brazil, East Africa, and Sri Lanka.
