This matrix specimen of brecciated limestone is host to several large, tabular calcite crystals along with many small ones. the basal hexagonal faces are milky white while the short prismatic faces are glassy and gemmy so that you can look right down into them, presenting an "Oreo" effect in ghostly white! The largest of these calcite crystals is 5.5 cm across and they are nearly pristine - seemingly unusual for this find, in a cluster so large (most had MAJOR damage and had to be selected carefully) .
