What are gemstones?

When we speak of gemstones, we usually mean minerals that have been cut and polished.

Treating, cutting and valuing gemstones

Gemstones are valuable because they are a rare and desirable commodity. They can be treated to improve their appearance and saleability and faceted gemstones reveal the inherent qualities of a mineral.

Origin of gemstones

Gemstones are a product of the earth and gem deposits are classified according to the geological environment in which they formed.
