Gemmy prismatic crystals of Mimetite thickly coat four crystals of Tennantite to 1.6cm. The Tennantite crystals are on a bed of Quartz crystals. The Mimetites are transparent lustrous yellow, measuring to just over 0.3cm in length. The Quartz is prismatic with elongate crystals to almost 1cm length of a white-creamy colouration. A superb combination specimen, with real sparkle.
