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.
I have always been skeptical of ordering fine items online for fear of disappointment. Today, Thursday April 26, I received the blue sapphire which I ordered on Monday, April 23. Not only was I impressed with the rapid delivery of my sapphire, but I was very pleased with the way the stone was packaged and protected. The sapphire itself was far better quality than I had anticipated and it will make a beautiful centerpiece for the ring I'm having made. Thanks so much for the great experience...
