More Info On natural diamond
The amount and quality of light reflecting from the surface of a gemstone is known as its lustre. For example, vitreous is a "glass-like lustre" and adamantine is the 'very high lustre' seen on the surface of a polished diamond. The lustre of gemstones are also described in terms that are easy to relate to, i.e. metallic, resinous, pearly, silky, greasy, waxy and dull. It is usually found (with exceptions) that the harder the gemstone material the brighter the lustre. The quality of the surface polish is important, as a poor polish will display a poor lustre.
