The Excitement of Cutting Nobbies
Cutting raw black opal from Lightning Ridge is a highly skilled art that often requires years of experience to master. Unlike boulder opal which is easily visible on its host rock, this specific rough material often comes in the form of nobbies. These are small rounded claystone nodules that completely encase the precious opal inside. The valuable color bar, the dark potch layer, and any sand inclusions are entirely hidden beneath a dull crusty outer skin. The geologists at Geoscience Australia document that these unique claystone nodules form exclusively in the sedimentary basins of New South Wales.
Revealing Hidden Fire
Lapidaries must carefully grind away the outer layer using specialized diamond wheels. The cutter works very slowly to expose the color bar without grinding through it. The speculative nature of this process is exactly what makes cutting rough opal lightning ridge specimens so incredibly exciting. During polishing, a cutter might uncover unexpected pockets of red and rainbow fire, or they might encounter natural sand holes and internal fractures. Once cut and polished perfectly, these stunning solid stones are ideal for bespoke jewelry creations.
