Night and day, the changing hues of Alexandrite enchant the eye and fuel the imagination. Its mesmerizing color swings - from red to green depending on the light source - makes it the most famous and popular of all color-change stones.

First discovered in the Ural Mountains of Russia in the 1830’s, this gem helped celebrate the coming of age of Czar Alexander II. The name Alexandrite was bestowed on this newly found Chrysoberyl as a tribute to the young royal, and its green and red colors were reflective of tsarist Russia.

The hypnotic beauty of Alexandrite makes it a gem prized by connoisseurs. While Russia continues to be a limited source, Brazil is Stuller’s primary source for Alexandrite. Madagascar, India and Sri Lanka are other global sources for this alluring gem. Sizes above 1ct are rare and fine quality gems are often more expensive than comparably sized Ruby or Sapphire. Alexandrite that display a 100% change in color from red to green are most desirable. While we offer a consistent supply of smaller, calibrated Alexandrite, as shown in this catalog, larger sizes are available as part of the Stuller Notable Gems™ collection.

Because of its ability to change dramatically in shifting light, Alexandrite is associated with balance in life, self-esteem, and the ability to experience joy - powers that, according to legend, the stone may impart to its wearers. Often used to celebrate June birthdays, Alexandrite also commemorates the 45th and 55th wedding anniversary. With a hardness of 8.5, Alexandrite is an excellent gem in terms of wear. Its natural (untreated) colors are perfect for those who look for a unique expression of self.
