What is Gem Stone Jewelry?
Gem stone jewelry is jewelry made with a rock, mineral or petrified substance that is cut and polished to provide a beautiful appearance. It is a gem stone’s beauty that differentiates it from other rocks and makes it desirable to jewelry lovers. The stones are usually mined from the earth, then cut and polished to prepare them for sale. Some gems are treated to enhance their beauty. For example, brown zoisite is heat treated to produce the attractive blue gem tanzanite, and emeralds are frequently treated with oil, wax or resin to make surface flaws less noticeable.
