Marcasite is a natural mineral used in jewelry. It is a light and brittle mineral that is often mistaken for pyrite. Pyrite and marcasite have the same chemical formula, but different crystal system, thereby making them two separate minerals. In jewelry, pyrite is used as a gem while marcasite is not. It is a mined stone and when used in jewelry, marcasite is cut and shaped very much like diamonds.

Silvexonline.com carries a whole line of marcasite jewelry made strictly out of Grade A marcasite from Thailand. When our marcasite jewelry is created, we oxidize the silver to prevent future tarnish. This process gives all of our pieces the antique or vintage look that is very popular today.
