Blue Diamond

Diamond, the hardest known natural material, is named from the Greek "adamas", meaning invincible. A diamond is a transparent crystal of tetrahedrally bonded carbon atoms. Diamond is famed not only for its exceptional hardness, but also for its high refractive index and high dispersion of visible light - the ability to split white light into its component colors.

Diamonds can occur in almost any color, though yellow and brown are by far the most common. Diamonds with a detectable hue other than yellow or brown are known as colored diamonds. If the color is strong enough, a stone may be referred to as a fancy colored diamond by the trade. Colored diamonds contain impurities or structural defects that cause the coloration, while pure or nearly pure diamonds are transparent and colorless. Blue diamonds range from pale to highly saturated blue and often have a blue-green color.

Approximately half of the world's production of diamond comes from central and southern Africa, with other deposits found in Canada, India, Russia, Brazil, and Australia.

Greatly enjoyed my experience and am impressed as always by the selection available. Really solid website design as well, it’d help for ease of searching if multiple price ranges could be selected or any price range you want.

Everything was good about this order except I was a little disappointed in the product because it was so small. This is the first time that I have ever bought a gem so I was very unfamiliar with the sizes mainly because measurements were in metric.

Purchase process is easy. Make the selection online and pay for it. About a week to 10 days later the stone shows up. Very easy and on time.
