Marcasite Jewelry

Marcasite jewelry is well known for its unique silver-gray shine - much darker than crystals or diamonds, but still just as beautiful and eye-catching. Marcasite jewelry usually has a multitude of small gems inlaid, as larger pieces of marcasite have become much more rare.

Marcasite was originally thought to be the same thing as pyrite, but was later discovered to have a unique crystalline structure, making it a close relative of pyrite instead - similar to how diamond and graphite are both different forms of carbon. This fascinating gem is making a comeback - find your next piece of marcasite jewelry above!
