Ring in yellow gold in SION style, with a 4.18 ct oval Ethiopian boulder opal cabochon, held by prong settings in hand-laminated wire. The boulder opal retains part of the ironstone matrix still attached to the stone — a natural substrate that lends each specimen a groundedness that free opal does not possess. The play of colour moves across this darker base with particular intensity: vivid, localised, wholly unpredictable. Each SION prong is a fine wire of gold, laminated, twisted, and individually shaped before being laid against the surface of the stone — transforming a structural element into an ornamental one. An exclusive piece for those who seek authentic artisanal mastery and a gemstone of irreplaceable allure.
