White lustrous steeply pyramidal spiky crystals of Calcite are seen grown over crystals of Amethystine Quartz from the Baia Mare mining area in Romania. Crystals of Calcite display a central core overgrown by micro-prismatic crystals of Calcite, giving them a Christmas tree appearance. Crystals of Amethyst are a gemmy light purple formed on a vein of white Quartz. A pleasing neat specimen from the mining area.
