The crystals display well-defined faces, broad terminations, and a vitreous luster, with translucent golden edges that catch the light. A contrasting cluster of pale, translucent crystals occupies a central cavity, while smaller vesuvianite crystals extend across the surrounding matrix. \u003cmeta charset=\"utf-8\"\u003eThe pale central crystal cluster is visually consistent with calcite.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eVesuvianite, also known as idocrase, is a complex calcium aluminum silicate that typically forms through contact metamorphism and metasomatic alteration of calcium-rich rocks.
