Calcite with Natrolite

A domed mound of overlapping, squat, nail-head Calcite crystals ranging from around 1.2 to 3.0 cm in diameter, but of relatively shallow thickness, from Stríbro in the Plzen Region of the Czech Republic.  The translucent fawn-beige crystals form saucer-like hexagonal crystals, with alternating broad and narrow faces and a three-fold Mercedes star termination.  The Calcite crystals towards one side are preferentially coated with micro-crystalline Natrolite of a greyish-cream hue.  A lovely Calcite from Stríbro with a true waxy lustre accompanied with Natrolite, a zeolite group member.
