Magnificent 3.18ct wide block flashing Black Opal

The color of this opal is in constant movement, smoldering and flashing through electric green and rich blood red with pops of gold and yellow. Its black hue amplifies these colors, and you can easily observe its play of color from arms length. This all natural opal measures 13.3mm x 11mm x 4.3mm, and was heated. Sourced from Welo, Ethiopia.
