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...
Excellent. Items were gorgeous and exactly as pictured. Ordered on Monday, rec'd. Thursday AM !! I liked the website and the details of the items. It was an easy, fast and clean transaction. Admitting here that I have purchased from GemsTV and found that some gems ordered were less than advertised. Now I am happy that I can see an exact picture of the item I am to receive.
