Lab Pigeon Blood Ruby Cushion Cut Three-Stone Ring with Trillion Diamond Side Stones | S925 Silver French Vintage

A deep crimson cushion between two white triangles. The ring that looks like it was made for a different century — and belongs in this one.

A cushion-cut lab-grown pigeon blood ruby — the most coveted colour grade in ruby gemology, a vivid, deeply saturated crimson-red with a warm undertone — sits in a six-prong setting at the centre of a classic three-stone trilogy ring, flanked on each side by a single large trillion-cut white diamond in a three-prong mount. The trillion cut — a triangular brilliant with curved sides and exceptional light return — is among the most distinctive side-stone cuts in fine jewellery: the triangle’s three equal sides and pointed corners create a bold, graphic silhouette that frames the cushion ruby with a directional, architectural precision that a round or pear side stone cannot achieve. The trillion diamonds’ triangular silhouettes point inward toward the ruby centrepiece, creating a sense of convergence and visual focus that draws the eye to the pigeon blood ruby’s vivid crimson. The cushion cut’s soft, rounded corners complement the trillion diamonds’ angular triangular silhouettes, creating a composition of deliberate contrast between the organic warmth of the cushion and the geometric precision of the trillion. The slender, polished band’s clean arc gives the ring a refined, French vintage profile that allows the three-stone composition to speak without interruption. This is the ring that earns its place as the most considered piece in any collection.

Why You'll Love It

• Trillion diamond side stones — two large trillion-cut white diamonds — triangular brilliants with curved sides and exceptional light return — frame the cushion ruby with bold, graphic triangular silhouettes; the trillion’s three equal sides and pointed corners create a directional, architectural precision that a round or pear side stone cannot achieve, and the triangular tips pointing inward create a sense of convergence and visual focus toward the ruby centrepiece
• Pigeon blood ruby colour grade — pigeon blood is the most coveted colour grade in ruby gemology, describing a vivid, deeply saturated crimson-red with a warm undertone associated with the finest Burmese rubies; the cushion cut’s rounded corners and deep pavilion create a stone of exceptional colour depth and warmth that appears to glow from within
• Cushion-trillion geometric contrast — the cushion cut’s soft, rounded corners create a deliberate contrast with the trillion diamonds’ angular triangular silhouettes; the combination of the organic warmth of the cushion and the geometric precision of the trillion creates a three-stone composition of exceptional visual tension and considered quality
• French vintage character — the combination of the cushion ruby’s romantic warmth, the trillion diamonds’ bold geometric character, and the slender polished band’s clean arc creates a ring with the considered, refined quality of a mid-century French fine jewellery piece; the French vintage aesthetic gives the ring a timeless character and historical depth
• Guilt-free luxury — lab-grown rubies share the same optical and chemical properties as mined stones, with a significantly lower environmental footprint
