Colorful Black Opal Carving, 1.78ct from Lightning Ridge, Australia Type_Opal Specimens this Australian opal is a1. 78ct, 11. 68x9. 86x3. 89mm from Lightning Ridge, Australia. Brightness: 3. 5 of 5; Body tone: N4, Black opal. This incredibly colorful opal is a special gem. The rough was not obvious to be shaped in traditional cabochon so I ended with shark tooth shape. From every angle there is different pattern and play of color is one of kind. This gem will make a unique piece of jewelry. *This opal is cut and polished by Lga from Ligas Creative Workshop.
