This is my sons favorite color pattern, small patches of intense color play that sparked like the stars in the sky. One 7.72 carats oval cabachon cut opal, cut grade very good, measuring 18 mm wide, 20.7 mm long, 4.7 mm deep; with very good polish and good symmetry. Large and vivid pin fire type color. Hydrophane type opal from Welo Ethiopia cut by Steve Moriarty. This opal has a very large appearance due to its shallower depth and because our opals prices are based on price per carat you get a larger look for your money
