An excellent and very representative specimen of the rare mineral Betekhtinite, a copper-iron-lead sulphide, from the Dzhezkazgan mining district in the Karaganda Region of Kazakhstan. Black metallic acicular crystals have grown in parallel to form a solid mass of vertical rods, occasionally overgrown with colourless micro-crystals of Quartz. This lovely small miniature/large thumbnail is mounted on a clear acrylic base.
