Description

Cosalite has a hardness of 2½ – 3 and a specific gravity of 6.86 – 6.99. It’s named after its TL, the Cosala Mine, in Sinaloa, Mexico, where it was discovered around 1868. It occurs in moderate-tempurature hydrothermal deposits, contact metasomatic replacements, epithermal replacements and pegmatites, according to WebMineral and Mindat. It’s since been found in hundreds of localities around the world, with ~40 in the US and 9 in Colorado, often found associated with Quartz, Gold, Pyrite, and other sulfides.

As these don’t come from Colorado, they’re slightly cheaper Gold-bearing specimens available for you to bring home and add to your collection from ColoRockCo for a natural representation of that rare element, or they could also be perfect for Bismuth, Lead, Iron or Sulfur, as well!

It almost needs not be said, but now that you know what Cosalite looks like when paired with Gold and Pyrite, be sure to keep your eyes out for a rock like this the next time you’re out on a hike and you may just discover your new literal Gold Mine!
