Welo Ethiopian black, opal sterling silver ring

Genuine, beautiful black opal. In reality it's very dark not essentially black. You have a lot of blue and then you have green flashes but they called this a black opal because of its darkness. Guaranteed 925 Sterling silver. Very beautiful piece with a full sterling back. In the picture, I have it definitely near the light but depending what light you're in it could look more on the darker side. New. Size 6.5.
