Stone Name -: Natural Ethiopian Opal Round Cabochon Super Quality Calibrated Stone size -: 4mm Number of Pcs -: 130 Weight – 22.30 carat ***All cabochons in my stone shop are cut by my own hand with love and care. I pay special attention to perfect evenness on every angle of the stone. This makes the gemstone easy to set with a bezel. The bottoms of each are flat and have a very slight level cut into the bottom edge. This cut serves to minimize the chance of chipping when setting into hand fabricated metal bezels or wire wrapping.
