More About Alexandrite

What is alexandrite?

Alexandrite is a very rare, transparent gemstone that appears green-blue in daylight but changes to red-violent under incandescent light.

It is one variety of the mineral chrysoberyl.

Due to its rarity and unique color-changing ability, naturally occurring alexandrite is extremely expensive, often surpassing even the price of precious stones like emeralds and diamonds. A small gemstone can reach a very high price. For this reason, synthetic alexandrite is popular for jewelry making.

Alexandrite is one of the birthstones for the month of June. It is associated with the zodiac signs Gemini and Cancer. It is also the gemstone for a 55th wedding anniversary.

Example: Having an alexandrite ring is almost like having two different pieces of jewelry—one with a green stone and one with a red stone.

Where does alexandrite come from?

The first records of the word alexandrite come from the 1830s—around the time it was first discovered in the Ural Mountains of Russia (making it a relatively modern discovery in the world of gemstones and minerals). It’s named after Russian Tsar Alexander I, who was tsar from 1801–1825. The suffix -ite is used to denote a mineral.

Alexandrite is a variety of the mineral chrysoberyl, which consists of beryllium aluminate. It is found naturally in Russia, Sri Lanka, East Africa, and Brazil, but natural alexandrite is very rare.
