Prized since ancient times, a fine emerald can be more expensive than a high quality diamond of the same carat weight.
Emeralds are green members of the popular beryl family of minerals. The green color occurs when pure, clear beryl contains either chromium or vanadium.
Beryl occurs in many other colors, with shades dependent on the impurities that Mother Nature has mixed into its otherwise clear formula. Blue beryl is known as aquamarine. Pink shades of beryl are known as Morganite. Yellows are often simply called yellow beryl and golden beryl. The term bixbite refers to red beryl, a variation that’s even more rare than emeralds.
