Adamite is a minor ore of zinc and does not occur in many places. In the US, small colorless crystals are found in California and Utah. The most magnificent occurrence is in Mexico, where large, beautiful and highly fluorescent examples occur in all different colors. Its bright green fluorescence, high luster and density, and double triangle terminations make it an exquisite specimen. Adamite is considered useful for disorders of the heart, lungs and throat, and has been used to treat cyclical emotional disorders associated with certain hormonal changes. The average adamite price is $5 per gram.
