A 6.55ct Lightning Ridge Black Opal Nobby rub, N4, B4 Very Bright, with potential to be more. Black potch is present in some areas of the face, separating the flagstone, adding to the character, making the piece one of a kind and attractive. This bar thins slightly through the centre, leaving that section a touch more subdued than the rest.
Outstanding colour in daylight, firing on black. A stunner as a pendant on someone's chest that would catch light from any direction, or slice it into small ring stones that will blaze on their own.
Authentic. Rare. Unforgettable.
