Cobalto Calcite Crystals

This is an extra fine designer cabochon of Cobalto Calcite  dolomite crystals. African material. This stone features an outstanding display of dark pink CC crystals. The dark green crystals are barely visible in hand. Don’t know what they are, but under a loop they look emerald green. In hand, this stone is NOT as bright purple as shown in the photo.  More like a dull purple.  FUN STONE. Flat back.  Visible matrix on the shoulders with a high satin polish.  SIZE: 44.3 x 18 x Shoulder height varies, Top 7.3 MM, Bottom 3.5 MM. Thanks for taking time to look.
