Magnificent 3.06ct teal and green flashing Black Opal

The color of this opal is in constant movement, delivering a rolling ribbon pattern in electric greens and turquoise with pops of golds and rich cobalt blues. Its black hue amplifies these colors, and you can easily observe its play of color from arms length. This all natural opal measures 15.2mm x 9.4mm x 5.3mm, and although heating is a common treatment, this example is unheated. Sourced from Welo, Ethiopia.
