Calcite

The Elmwood mine at Carthage in Tennessee, USA, is one of those localities that every mineral collector is familiar with because it is one of the world’s most iconic and instantly recognisable Calcite localities. This specimen is a splendid miniature version of the large museum-scale golden-sherry Calcites.  The 5.4 cm long double-terminated twinned Calcite has a central translucent creamy core where the twins join with a clearly define re-entrant angle, and gradually become more transparent progressing towards the sharply terminated tips.  This excellent crystal is acutely perched on a sliver of dolomite/limestone matrix encrusted with snowy-white curved rhombohedral Dolomite crystals, themselves overgrown with small golden-sherry Calcite crystals.
