A gemstone or gem also called a precious or semi-precious stone or jewel is a piece of mineral which in cut and polished form is used to make jewelry or other adornments.However certain rocks, such as la pis lazuli and organic materials such as amber or jet are not minerals, but are still used for jewelry and are therefore often considered to be gemstones as well.

Emeralds are fascinating gemstones. They have the most beautiful, most intense and most radiant green that can possibly be imagined: emerald green. Inclusions are tolerated. In top quality, fine emeralds are even more valuable than diamonds.
