Alexandrite is a very rare and highly valuable gemstone, and until recently was extremely difficult to obtain due to its rarity. The only other color changing gemstones are Color-change Garnet and Color-change Sapphire. Alexandrite is softer than Sapphire and harder then Garnet.

However, new sources in Brazil and Tanzania have made this gemstone available and more mainstream on the gemstone market. Alexandrite was first discovered in Russia in the early 1800's. Named in honor of Alexandar Nicholavich (Russian Czar Alexander II).

A short distance across the border, in Slovenia, a similar occurrence exists at the mines in Mežica.
