Strontianite is a rare carbonate mineral (strontium carbonate) and one of only a handful of known strontium minerals. Crystals are rarer than the massive forms. Typical specimens have spiky, minute crystals in radiating aggregates or tufts, exactly as you see here in this fine miniature from the Minerva. Ex. Consie Prince Collection.
