Lab Sapphire Emerald Cut Trillion Diamond Three-Stone Ring | S925 Silver Adjustable

Deep blue between two white triangles. A three-stone ring that lets the cuts do the talking.

A large emerald-cut lab-grown sapphire in deep royal blue sits in a four-prong setting flanked by two trillion-cut diamonds — their triangular points facing outward, creating a bold, geometric three-stone composition of exceptional clarity. The emerald cut’s clean rectangular lines and the trillion’s sharp triangular silhouette create a deliberate contrast of shapes that gives this ring a distinctly architectural quality. No halo, no pavé — just three stones, three cuts, and a polished adjustable band that fits any finger.

Why You'll Love It

• Trillion-cut diamond flanks — triangular trillion diamonds on each side of the sapphire are a far more distinctive choice than the standard round or pear side stone; their sharp points and flat table create a geometric contrast with the rectangular emerald cut that gives the ring a genuinely architectural quality
• Emerald-cut sapphire centrepiece — the rectangular step-cut maximises the sapphire’s deep royal blue colour and creates a bold, clean focal point; the long, open facets of the emerald cut give the stone a depth and clarity that a brilliant cut cannot replicate
• No-halo three-stone setting — the absence of a halo keeps the focus entirely on the three stones and their contrasting cuts; a more confident, considered design choice that lets the geometry speak for itself
• Adjustable band — fits any finger without sizing; ideal for gifting or for those who prefer flexibility in their jewellery
• Guilt-free luxury — lab-grown sapphires share the same optical and chemical properties as mined stones, with a significantly lower environmental footprint
