Gorgeous rainbow colored 5.90 CRT Natural black opal cabochon originating from Ethiopia. This measures approximately 15.7 x 15.4 x 15 mm in a trillion shape and is approximately 6.4 mm deep.
This has no damage or chips and is in great condition. There is one extremely tiny surface scratch we have magnified in the photos, but it is hardly noticeable by eye. This stone has an excellent play of color and displays nearly every color of the rainbow. This is a naturally earth mined gemstone and has been smoke treated to enhance color.
