Marcasite Pyrite

Marcasite (White Pyrite) - Domestic

I was taken to a place by a mineral enthusiast, and while thinking Who would go to a place like this?, I collected this from a steep cliff.

Marcasite (white pyrite) rough is an allotrope of pyrite, with a pale brass color and metallic luster.

This product, marcasite (white pyrite), is a slightly broken piece of a characteristic nodule. From the broken surface, you can see fine, sandy white pyrite densely packed. I believe breaking it further would reveal more interesting features, but I'm offering it in this state so you can enjoy the metallic color when it's broken.

This type of marcasite (white pyrite) is very rare.

Marcasite (white pyrite) oxidizes over many years, so to maintain its current condition for a long time, we recommend storing it in a sealed, dry environment.

The following is from a Google search.

White pyrite (marcasite) is a mineral with the chemical composition FeS? (iron sulfide) and is an allotrope of pyrite (different crystal structure with the same components). It has a silvery-white to pale yellow or cream-colored metallic luster and is found in orthorhombic crystal aggregates such as spearhead-shaped, fan-shaped, and spherical. Its hardness is 6-6.5, harder than iron, but it is sensitive to moisture and requires careful storage.

I'm offering a small portion of what I collected by chance when I was taken there. Since I can't go myself, I won't be able to list many items. As this is a rare mineral, I cannot disclose the location or the details of its extraction. Please take this opportunity.

Thank you for looking.
