Rare Gemstones II:

Named for Tsar Alexander II of Russia, this exceedingly rare gemstone was thought to be mined out after the original deposits, found in 1830 in Russia’s Ural Mountains, were nearly exhausted.

Alexandrite is a color-changing gemstone: its hue shifts from red to green depending on the light it’s exposed to.

Recent finds in Brazil, East Africa and Sri Lanka have brought this stone back on the market, but it is still one of the world’s most coveted stones.

Composition: Beryllium, Aluminum, Oxygen | Market Value: $12,000 per carat.

Same crystal different color….
Alexandrite is one of June’s multiple birthstones (not sure why June gets so many good ones…) An exceptionally rare variety of the mineral Chrysoberyl, Alexandrite is famous for its color changing property- the most valuable Alexandrite, from the Ural Mountains in Russia, will display a dramatic color change from red to green depending on the light source.
The crystal pictured above is Brazilian, and the color change goes from green to purple (I actually couldn’t capture the depth of either hue with the camera- the color change is even more significant in person.) This incredible, natural, uncut Alexandrite specimen displays penetrating twin crystals that intersect to form a six-sided rosette that is Classically Chrysoberyl. 👌RX-107, $3,330.
