15.73 carat Pezzottaite Freeform

23.13mm x 15.85mm x 6.85mm


Award-Winning competitve faceter Brett Kosnar cut this gem from an original piece of rough weighing 34.195 carats.  This freeform geometric shape has great color and brilliance from multiple angles, and is completely unenhanced.  Traditional enhancement with a liquid medium would further improve the appearance.


This was labeled the Crimson Aquarium because the gem has excellent crystallinity and a sizeable table through which one can view a seabed of inclusions.
