CB-0059 Peloncillo Agate This is an Oval shaped Peloncillo Agate cabochon, but is not calibrated. It is 23X16.7X5.2mm and weighs 14.5 carats. This cabochon should fit a standard 23X17mm bezel cup or prong setting and will make a very nice small Pendant or a Ring. A Wire Artist could also create a very special piece of jewelry with this stone. $2.20
