Emerald is a light-to-dark green gemstone, a form of the mineral beryl that derives its color from the elements chromium and vanadium. It is often irradiated for clarity. Because the metamorphic rock in which emeralds grow limits their size, large emeralds are particularly rare. Deeper green emeralds are the most highly valued, and small inclusions are not as detrimental to the value of an emerald, as they are to many other gems.
Emeralds are often oiled to improve their apparent clarity and to soften the appearance of inclusions. This process is routine, albeit generally not disclosed. The emerald is the state gemstone of North Carolina and is said to be the seasonal gem of Spring.
Supposedly, the emerald can strengthen its wearer’s memory, quicken the intelligence, and assist in predicting the future. It is also supposed to aid in physical and emotional healing. Emerald is a symbol of immortality and faith.
According to legend, Satan lost an emerald from his crown when he fell from Heaven, a gem which was much later found and shaped into a bowl by the Queen of Sheba and sent to Nicodemus.
