Emerald is a stone of love and romance. Emerald derives it’s glorious green color from the presence of chromium and vanadium. Emeralds are rarely flawless, therefore stones are often enhanced by oiling them to hide the imperfects. As well, the step cut (or emerald cut) is used to maximize the stone.
The proper name for the emerald is beryl, but there are different colors of beryl. Emerald Green is the color as well as the stone. When blue is added to the green, the beryl is known as Aquamarine.
An emerald of the right shade of green can be more valuable than a diamond. The finest emeralds are found in South America in Colombia, where they have been mined for over 400 years. The gem was a favorite in pre-Columbian Mexico and Peru, where it was cut in intricate designs. The treasure taken back to Spain by early explorers included emeralds.
