Brilliant flashing 3.17ct semi-black Opal

The floral flashing of this piece rolls across its surface in a non-stop display of vivid pinks, oranges, yellows and greens while its rich semi-black hue enhances its flashing, adding vibrancy with its juxtoposition of color. It has a medium domed cabochon cut with incredible size, measuring 11.3mm x 9.5mm x 6.3mm, and is finished with a glistening liquid luster. This is an untreated example. Sourced from Welo, Ethiopia.
