Semi-Precious Jewelry

A gemstone or gem, also called a precious or semi-precious stone, is a piece of attractive mineral, which — when cut and polished — is used to make jewelry or other adornments. For the past several hundred years, gemstones have been broken down into two categories; precious and semi-precious. The origin of the gemstone does not affect its categorization as precious or semi-precious. Rubies, sapphires and emeralds are always precious stones, while other gems are considered semi-precious.
