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.

I could not find the price and size ranges I need. It would be good if you had a birthstone package for a designer.

An incredible selection of gemstones at a wide range of prices. Some fantastic cuts - unlike any I have seen anywhere. It’s fun to look even if there is no intention to buy - if you can resist
