A classic specimen of lustrous and finely terminated black Cassiterite crystals are surrounded by light chocolate-brown lozenge shaped Siderite crystals and stubby acicular colourless and clear Quartz crystals. The Cassiterite crystals, of which there are about thirty, range between about 7 to 12 mm across, with mirror-bright faces and on examination are a translucent deep clove-brown. This is an excellent display specimen of very fine Cassiterite crystals. From the San Antonio Mine, Loayza Province, Bolivia.
