M316 Marcasite

M316 Marcasite


Here’s a new item, a very cool specimen of Marcasite. This interesting piece measures 4 1/2″ x 2″ x 1/2″.  This pretty specimen has great color and neat structure.  As an added bonus it will fluoresce a beautiful orange under a SW/UV light. This would be a wonderful addition to any collection.

The mineral marcasite, sometimes called “white iron pyrite”, is iron sulfide with orthorhombic crystal structure. It is physically and crystallographically distinct from pyrite, which is iron sulfide with cubic crystal structure. Both structures do have in common that they contain the disulfide having a short bonding distance between the sulfur atoms. Marcasite is lighter and more brittle than pyrite. Specimens of marcasite often crumble and break up due to the unstable crystal structure.
