Black opal is distinguished by a dark, gray-to-black body tone, which provides a dramatic contrast. This deep background acts like a canvas, making its vibrant internal flashes of color—such as red, blue, green, and gold—appear significantly more vivid than in lighter opals.
Natural black opals are very rare. All black opal at Calcifur's Crystals are heat treated white opals.
This stone is approximately 9x7mm and is set into an adjustable sterling silver poison ring. It is adjustable and will best fit sizes 7 - 9.
