Collectors UNTREATED 6.35ct rainbow block patterned semi-black Opal

This is a fascinating opal. It has a rich semi-black body color with an amazing rainbow block pattern that produces vivid play of color in both bright and dark lighting. That means you don't have to wait for the right to see its brilliant display, because every lighting is the right lighting with this piece. But here is what makes this opal truly fascinating. On one side of this opal there is a section that is lighter than the rest, and where the dark and light colors meet is where the lions share of this radiant color converges. Even on the back! It shows beautifully in the video, but in hand the play of color is much more dramatic. Trust us, when this one-of-a-kind opal arrives, you will impressed. It measures a whopping 14.5mm x 11.4mm x 6.7mm, and was finished with a glistening liquid luster. Sourced from Ethiopia. Untreated!
