Lab Sapphire Oval Cut Six-Prong Solitaire Open Ring | S925 Silver Deep Royal Blue Adjustable Engagement-Style

A vivid deep royal-blue oval held by six silver prongs on a plain tapered band. The ring that lets the stone speak entirely for itself — and fits any finger.

A large oval-cut lab-grown sapphire in vivid, deeply saturated deep royal blue — its considered deep, near-midnight blue saturation creating a stone of exceptional considered colour authority and chromatic depth — sits in a six-prong solitaire setting of exceptional considered classic authority: six individual silver prongs, each rising from the band’s shoulder to secure the sapphire at six equidistant points around its girdle, the six-prong construction’s considered classic form giving the ring a sense of exceptional considered solitaire authority and fine jewellery heritage. The six-prong setting’s considered classic construction — six prongs, no halo, no additional metalwork — gives the sapphire a sense of exceptional considered presence and unobstructed colour authority, the deep royal blue’s vivid saturation visible from every angle without interruption. The oval cut’s considered elongated form creates a stone of exceptional considered visual presence and finger-elongating character on the hand. The plain tapered silver band — a smooth, undecorated band that narrows gradually from the shoulder toward the centre — gives the ring a sense of exceptional considered design restraint and considered focus on the sapphire’s deep royal blue. The open adjustable band can be gently resized to fit any finger — no sizing required.
