A semi-precious stone is also known as a gem or gemstone, which is a portion of mineral, which, in refined and cut form, is used to create jewelry or other embellishments. There are also organic resources or precise rocks that are not minerals (for example jet or amber) that are also used for jewelry and would also be considered to be gemstones, as well.

Precious stones are diamonds, sapphires, rubies and emeralds. All other stones are considered semi-precious stones.
