No stone puts on a show quite like opal, and the Princess Diana Inspired Opal Ring in platinum plated sterling silver gives it the stage it deserves. Light enters the opal stone, bounces off its silica layers, and comes back out as a kaleidoscope of colour, flashes of every hue shifting with every move of the hand. It symbolises truth, purity, and hope, and it does all of that while looking completely extraordinary. Platinum-plated sterling silver keeps the setting cool and neutral, the perfect backdrop that lets the opal's internal colour play take over completely. The halo of zircons frames the oval cut opal with white brilliance, grounding the stone's shifting colours in structured sparkle. Oval cut lengthens the finger and gives the ring the same elegant, considered proportion that made Princess Diana's halo silhouette the most referenced design in jewellery history. For October birthdays, nothing else even competes.
