Substantial 4.19ct Welo semi-black Opal

This opal is simply amazing. It has a rich, earthy semi-black hue with vibrant play of color that rolls across its surface in stormy clouds of rich greens with pops of red that are intertwined with touches of turquoise and misty whispers of violet. The luster of this opal glistens in a liquid display, creating a shimmering effect on the colorful flashing that is already amplified by its dark body. Measuring 14.3mm x 9.2mm x 5.8mm, it has fantastic size, and is untreated. Sourced from Welo Ethiopia.
