Finding awesome rocks, minerals, crystals, and fossils is hard. We've partnered with trusted suppliers, collectors, and geologists to ensure that the rocks we send you were ethically sourced. We believe that removing precious materials from any location must be done in a way that considers everybody in the supply-chain; from the experts who know how to properly grade and inspect the materials to the people whose land they're being removed from. Everybody is treated fairly and guaranteed excellent compensation for their work.
