Botryoidal Marcasite (Misgaran Mine, Adraskan District, Herat, Afghanistan)
Marcasite a.k.a. white iron pyrite, is a type of iron sulfide with orthorhombic crystal structure.
This makes it different from pyrite, which is a type of iron sulfide with a cubic crystal structure.
Note: this is pure marcasite. I make this distinction because, very often, we find marcasite included in chalcedony.
The Misgaran Mine is an ancient mine which has been worked for the longest time. It is rich in tin, and has been dug down to the Early Cretaceous layer of sandstone, siltstone, shale and limestone.

For every $15 spent, we will plant 1 tree to offset the carbon cost of mining, shipping and packaging crystals.
These are real and natural products, and so might have some flaws or imperfections. We have done our best to pick the best pieces available, but nature is often imperfectly perfect. Therefore, please only make the purchase if you are alright with this.
