There are opal rings, and then there’s this. The elongated black opal is electrified by its blue, red and green flashes. The platinum setting, although a simple bezel from afar, in fact mimics in metal the joie de vivre of the opal with head-to-toe hand engraving. Opal lovers take heed – for this one’s hypnotic and a short glance inevitably becomes a long reverie. Trust us, we’re still waiting to be roused. Made by San Francisco firm Walton & Co. c. 1920 whose designs often feature the most exquisite opals such as this.

This ring is in excellent antique condition. Presently a size 6 and can be resized
