1.7" Danburite Crystal Cluster with Pyrite - San Luis Potosi, Mexico

This is a cluster of danburite crystals that were collected from San Luis Potosi, Mexico. There are small pyrite crystals that can be found scattered throughout the danburite crystals.

Danburite is a calcium boron silicate mineral that is often found as transparent, colorless crystals. Depending on impurities present, it can also bear tan, grey, white, yellow, brown, orange, and pink coloration, and in some cases can be found encrusted in a layer of druzy quartz. Danburite earned its name from the town it was first described in: Danbury, Connecticut.

Chemical Formula - CaB₂(SiO₄)₂

The mineral pyrite, also known as iron pyrite, is commonly referred to as Fool's Gold because its metallic luster and pale brass-yellow hue give it a superficial resemblance to gold. In the old mining days, pyrite was sometimes mistaken for gold.

It is the most common of the sulfide minerals with the chemical formula FeS2. Pyrite crystals occur in many shapes and habits, including cubes of all sizes, penetration twin cubes, pyritohedral clusters and as small druzy crystals that can exhibit a beautiful glistening effect.
