The minerals we sell originate from Uruguayan soil, specifically in the department of Artigas .

These were formed approximately 140 million years ago due to volcanic activity : bubbles of steam and gas are trapped in the lava as it cools and create cavities in the rock, crystallizing its components, giving rise to the geodes and druses of amethysts or agate that are different types of quartz.

A geode is a rock cavity, usually closed, and completely lined with crystals (often automorphic) and other mineral matter. It is a composition of magmatic, crystalline and/or sedimentary formations. While a druse is a flat base of crystal formation that may have arisen from a geode or from the outside of the stone.
