piece of mineral used to make jewelry From Wikiquote, the free quote compendium
A gemstone (also called a gem, fine gem, jewel, precious stone, or semi-precious stone) is a piece of mineral crystal which, in cut and polished form, is used to make jewelry or other adornments.
Dear, I took these trackless masses
Fresh from Him who fashioned them;
Wrought in rock, and hewed fair passes,
Flower set, as sets a gem.
