This is a cluster of gemmy, cognac colored calcite crystals, to 14 cm across, on a matrix of gray limestone. The vertical crystal is twinned and doubly-terminated although there is very minor bruising at the upper termination culminating in a backwards-leaning cleave at the tip. There is a slight cleave on the leftmost termination of the left crystal, as well...thee cleaves are really out of sight as you display it, but as a calcite collector I have to note them and downgrade the price...making this a very fie large display piece at a cost that would not have seemed inappropriate even 20 years ago.
