Rainbowsurge - A boulder opal ring that feels like a kaleidoscope bursting out of a thick silver band, its broad‑flash colours shifting in wild, saturated waves as though the whole stone is surging with rainbow light. The weighty, flowing silver design makes it feel premium and sculptural - a proper heirloom piece with that “all colours at once” opal magic.
This stunning Australian Boulder Opal ring features a vibrant round cabochon set in an elegant 925 silver waves‑style band.
Bursting with blue, green, orange, red, pink and yellow broad‑flash colour, this opal is a true showstopper - the kind of stone that shifts dramatically with every movement.
The silver waves band adds a soft, flowing aesthetic that complements the opal’s natural movement of colour.
Sourced directly from the miner and polished to a high shine, this opal has a brightness level of 5, making it one of the most vivid and lively stones in your collection.
A premium, heirloom‑quality piece for anyone who loves bold, colourful gemstone jewellery.
