Unique and Classic Black Opal Lightning Ridge, Australia This unique and unusual cabochon of true black opal has been fashioned by the gem cutter as in a lozenge-shaped outline--a rather unusual and elegant shape.
Black Opal is Australia’s national gemstone. Found in the Lightning Ridge area in northwestern New South Wales, black opals are natural, solid stones that absorb scattered white light, giving it brilliant spectral colors.
Black Crystal Opal Lightning Ridge, New South Wales, Australia Vivid broad flashes of electric blue and green are seen in this fine black crystal opal. The size would lend itself to creating a fine pendant from this classic Lightning Ridge material.
