Gemstone By Zaheen Gems Export

A gemstone is a mineral, rock (as in lapis lazuli) or petrified material that when cut and polished is collectible or can be used in jewelry. Others are organic, such as amber (fossilized tree resin) and jet (a form of coal). Some beautiful gemstones are too soft or too fragile to be used in jewelry, for example, single-crystal rhodochrosite, but are exhibited in museums and sought by collectors.A gemstone is prized especially for great beauty or perfection. Hence, appearance is almost the most important attribute of gemstones. Characteristics that make a stone beautiful or desirable are colour, unusual optical phenomena within the stone, an interesting inclusion such as a fossil, rarity and sometimes the shape of the natural crystal.
