 | "Unusual locality specimen with pseudohexagonal twinned aragonite crystals to 8 mm covering a massive aragonite matrix. Aragonite forms interesting habits and can have a soft pretty color. Its modes of formation and relationship to calcite are both curious and intriguing. Aragonite is a polymorph of calcite, which means that it has the same chemistry as calcite but it has a different structure, and more importantly, different symmetry and crystal shapes.
