About Us
About Borussia Minerals
Established 2016
We started Borussia Minerals in 2016 to share the pieces that make us stop and look a little closer. We focus on Arizona minerals, from carefully selected specimens to crystals we recover ourselves at the Fat Jack Mine.
From Our Own Mine
The Fat Jack Mine
We acquired the Fat Jack Mine on June 7, 2025. It dates to 1880, and we collect smoky amethyst scepters there. Every so often, we find stolzite too — a lead tungstate mineral.
