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.

Gemstones are accurately portrayed and comes with a gemologist confirmation of authenticity (not appraisal) but still helps when I set in my settings to make and sell rings.

I would recommend gem select. They care about all details from description to quality to packaging to shipping. I specialize in turquoise so I would like more explicit provenance than "American"... Couldn't they give me mine or at least state? Never the less very classy. Also, their turquoise cabochons are very thick for good and bad. I cut many in half to make them more versatile and commercially useful. If one can't do that then you are going to have to settle for wire wrapped jewelry. I think that overall thy are a great resource.
