Emerald Gemstone By Gautam Diam

EmeraldEmerald is among the least enhanceable. It cannot be laser treated, heat treated, irradiated, or diffusion treated. Its only method of improvement is oiling , in modern times, a polymer resin impregnated into the body of the Emerald through surface fissures. Emerald is the brittlest stone among all gems.The amount of enhancement in emeralds is very minute as it is limited to avenues of entrance such as micro fissures on the surface of the stone, which sometimes appear during the process of cutting and polishing the Emerald. The polymer, or oil, has the same or close refractive index as the Emerald, allowing light to pass through thus making the micro fissures largely invisible to the naked eye.
