Lab Pigeon Blood Ruby Emerald Cut Square Halo Ring | S925 Silver Diamond Pavé Adjustable

Pigeon blood red inside a square of diamonds. On a dark surface, this ring looks like it is on fire.

A large emerald-cut lab-grown pigeon blood ruby in the most coveted red in the gemstone world sits in a four-prong setting within a square round brilliant diamond halo — round brilliant diamonds trace the full rectangular outline of the ruby in a tight, continuous frame, creating a bold, architectural square silhouette of exceptional brilliance. A round brilliant diamond pavé band carries the sparkle down each shoulder. Pigeon blood is the highest colour grade in ruby classification — a vivid, slightly bluish-red of exceptional warmth and intensity — and the emerald cut’s long, open step facets maximise the colour’s depth in a way that a brilliant cut cannot replicate. The open adjustable band fits any finger. At $166.50, this is the pigeon blood ruby ring that earns its place as the most striking piece in any collection.

Why You'll Love It

• Square diamond halo — round brilliant diamonds trace the full rectangular outline of the emerald-cut ruby in a tight, continuous square frame; the square halo format is associated with the great jewellery houses and gives the ring a bold, architectural presence that a round halo cannot achieve
• Pigeon blood ruby — pigeon blood is the most prized colour classification in the ruby world, describing a vivid, deeply saturated red with a slight blue undertone; the emerald cut’s open step facets maximise the colour’s depth and create a stone that appears to glow from within
• Emerald-cut centrepiece — the rectangular step-cut creates a bold, clean focal point within the square halo; the long, mirror-like facets give the ruby a depth and intensity that a brilliant cut cannot replicate, and the rectangular geometry of the stone echoes the square outline of the halo
• Diamond pavé band — round brilliant diamonds along each shoulder create a continuous frame of brilliance that connects the square halo to the finger; the ring catches light from every angle
• Guilt-free luxury — lab-grown pigeon blood rubies share the same optical and chemical properties as mined stones, with a significantly lower environmental footprint
