6.3Cts Lightning Ridge Black Opal Rubs Parcel, 4 Stones, Bright Greens And Blues. No better opal than black opal from lightning ridge. Very well priced parcel of blacks. One rub has only outer color with a black spot in the middle. The bigger one at 2.25Cts you may lose half of it if you don't keep the black spot on the corner. There are 3 small vivid gems here and one that may be not as good but will still make a good jewellery piece. Sand is not a problem will come off.
