Meet Basalt, an earth dragon. His egg (Australian boulder opal) matches the color of the ground it was laid in. With some flashes of emerald green throughout the egg, it makes me believe this boy will be a true treasure once he hatches!
Please see the other photos and video to view the color changing properties and the size of the opal against the band on a finger.
The finished ring will include a sterling silver bezel around the opal, as seen in the example photo.
