Everyone has heard of fool's gold or iron pyrite - a golden-colored mineral that looks just like gold, but is actually a mixture of sulfur and iron. Marcasite (sometimes called white pyrite or white iron pyrite) are actually pyrite crystals that are made into jewelry.
True marcasite, on the other hand, is a yellow-colored mineral formed from iron sulfite. It is a relatively soft stone which crumbles into powder after a period of time and, as such, does not keep well in gem form.
Marcasite, on the other hand, which is actually pyrite is used as jewelry, often in combination with other gems and metals like silver. It has been used for centuries and has become steeped in legends and pagan traditions. It is believed to be able to release an energy that can throw off or counter negative energies, improve one's ability to communicate, and protect those working in dangerous occupations.
Marcasite is brassy yellow in color, sometimes with a greenish tint or a multi-colored tarnish that is the result of oxidation.
Marcasite Jewelry
Marcasite gem stones are black with an iridescent quality when struck by light. One jeweler observes that quality marcasite stones have a brilliant silver color or a bright metallic luster; when cut with many small facets at the top, it will catch the light and glow like small diamonds.
Many jewelers use marcasite in combination with sterling silver and other stones in intricate designs that are reminiscent of earlier times - Art Deco inspired pieces with their intricate designs, nature-inspired pieces like leaves and vines, butterflies and bees, as well as mythical subjects like griffins, leprechauns, dragons and the like.
