A fine Australian opal cabochon lights up with an internal kaleidoscope possessing a rainbow of hues.

Powerful pops of color, including red (the rarest) and every spectrum in between, dance across the surface. The opal measures over 8 mm in diameter with a weight of 1.25 carats. It radiates color from every flick of the wrist and turn of the finger.

A frame of ten deep and perky old European and old mine-cut diamonds adds to the light and shows their total weight of 1.70 carats.

Dazzlers, their white color of H-I, and their clarity of VS2-SI1 live up to the standards of this gem-quality opal.

In a setting of 18k yellow gold, it is a resplendent antique halo or cluster ring. No power cord necessary.
