Discovered in Russia in the early 1800s, alexandrite is named for Tsar Alexander II and was the national gemstone of tsarist Russia. Natural alexandrite is an extremely rare gem. This gemstone has the ability to change its color from green to red depending on the light source as well as versions of purple and blue. It appears green in normal daylight and changes to a red to purplish-red in incandescent light. Alexandrite is a very unique and beautiful gemstone. A Mohs' hardness rating of 8.5 makes alexandrite a very durable and trouble-free gemstone. Most available alexandrite is lab-created for commercial retail.
