Alexandrite is a green or blue gemstone that turns red or purple under incandescent light. The more intense the color and the more dramatically the alexandrite shifts from one color to the other (without any brown bleeding over during the change), the more valuable the gemstone.

The largest alexandrites are measured in the tens of carats, however gemstones over five carats are rare. When purchasing alexandrite, pay attention to the clarity of the two colors and to the completeness of the color change. Alexandrite can be simulated with color-changing synthetic sapphire.

Protect alexandrite from scratches, sharp blows, harsh chemicals, and extreme temperatures. Be especially careful when remounting this gemstone as the heat from a jeweler’s torch may alter its color.
