Analcime with Calcite

Dean quarry is adjacent to the coast on the far eastern side of The Lizard Peninsula, south Cornwall.  This quarry has long produced a small suite of interesting minerals, some of which are zeolites.  This lovely specimen has ten perfectly formed snowy-white Analcime trapezohedron crystals on a bed of colourless and clear Calcite crystals.  Often the Analcime is fragile and somewhat weathered, but in this specimen the crystals are glassy, lustrous and vibrantly fresh.
