Alexandrite: Buy Loose Alexandrite at Affordable Prices from GemSelect

Alexandrite is one of the rarest of all colored gemstones and is famed for its color change from green in daylight to red under incandescent light. Fine faceted alexandrite over 1 carat is more valuable than sapphire, ruby or emerald.

Alexandrite is a variety of chrysoberyl, with an excellent hardness of 8.5 on the Mohs scale, placing it right behind sapphire and ruby. Alexandrite is rare because of its chemical composition. Chrysoberyl is colored by traces iron and titanium, but alexandrite is also colored by chromium, which gives it the emerald green hue in daylight.

The website is well organized and works fast forward and back. Plenty of filters. Each gem is described in detail and you receive the one pictured. Gem material info and sources available. I would like to see more specifics on sources besides country- at least region or state and in the US with Turquiose which mine. Thanks!

I had a great time searching all the lovely stones. This is my first precious loose stone purchase for my own work. I chose sapphire, and found some lovely briolettes. I wanted 3, but this set of 4 was perfect. Everything was quick and easy, and I'm excited.
