Lab Ruby Cushion Cut Three-Stone Ring with Pear Diamond Side Stones | S925 Silver Adjustable Trilogy

One deep red cushion between two white diamonds. The ring that has been the language of significant moments for over a century.

A cushion-cut lab-grown ruby in vivid, deeply saturated crimson-red — the cushion cut’s rounded corners and deep pavilion creating a stone of exceptional colour depth and warmth — sits in a four-prong setting at the centre of a classic three-stone trilogy ring, flanked on each side by a single large pear-cut white diamond with its rounded end facing outward and its pointed tip directed inward toward the ruby. The three-stone format is among the most enduring and considered constructions in fine jewellery: past, present, and future represented in a single ring, the two side stones framing the centrepiece with a directional elegance that a halo or cluster cannot achieve. The pear diamonds’ elongated teardrop silhouettes create a sense of movement toward the ruby centrepiece, drawing the eye inward and giving the ring head a dynamic, directional quality. The open adjustable band fits any finger without sizing — gently squeeze or expand to fit — making this ring the ideal gift and an equally ideal personal purchase. At $189, this is the ruby trilogy ring that earns its place as the most meaningful piece in any collection.

Why You'll Love It

• Classic three-stone trilogy format — one cushion ruby flanked by two pear diamonds in the most enduring and considered construction in fine jewellery; the three-stone format’s symbolic resonance — past, present, and future — gives the ring a depth of meaning that a single-stone or halo ring cannot achieve
• Pear diamond side stones — two large pear-cut white diamonds with rounded ends facing outward and pointed tips directed inward toward the ruby create a sense of movement toward the centrepiece; the pear diamonds’ elongated teardrop silhouettes frame the ruby with directional elegance and give the ring head a dynamic quality that round or oval side stones cannot achieve
• Cushion-cut ruby centrepiece — the cushion cut’s rounded corners and deep pavilion create a stone of exceptional colour depth and warmth; the vivid crimson-red appears to glow from within, and the cushion’s soft, rounded silhouette creates a focal point of exceptional visual warmth within the three-stone composition
• Open adjustable band — no sizing needed — the open band ends allow the ring to be gently adjusted to fit any finger size without sizing; the adjustable construction makes this ring the ideal gift — no ring size required — and ensures a comfortable, secure fit for any wearer
• Guilt-free luxury — lab-grown rubies share the same optical and chemical properties as mined stones, with a significantly lower environmental footprint
