It is physically and crystallographically distinct from pyrite, which is iron sulfide with cubic crystal structure. Both structures contain the disulfide S 22− ion, having a short bonding distance between the sulfur atoms.The mineral marcasite, sometimes called white iron pyrite, is iron sulfide (FeS 2).

This mineral, from which the jewel takes its name, was believed to be marcasite, but this is a misnomer. The actual mineral, although similar in character, is actually pyrite, which is closer in texture, and is capable of receiving a more brilliant polish.mineral name; subsequent letters are selected from the mineral name.

Pyrite has the same chemical formula as the rarer mineral Marcasite, but it crystallizes in a different crystal system, thereby classifying it as a separate mineral species. Aggregates of iron sulfide (FeS 2 ) where the crystal structure cannot be determined without complex analyzing material may be wrongly labeled by dealers.Johnathan Hill used the name marcasite in 1771, but his usage was also indiscriminate and was a term for any massive "pyrites" or "mundic".
