RARE Harlequin Color Combination 13mm Lightning Ridge Black Opal

Dimensions (approx mm): 13mm x 4mm x 2mm
Body Tone: 2N
This stylised-marquise shaped opal from Lightning Ridge has a lovely blocky pattern arrangement. The unusual combination of colours dance across the surface and it has strong clarity. This piece seems larger and heavier than a stone under a carat. A RARE gem and indeed a unique COLLECTOR’S SPECIMEN.
