Lab Pigeon Blood Ruby Cushion Cut Double Halo Ring with Pavé Split Shank in 925 Sterling Silver

Vivid magenta-red in a double frame of white fire — the ring face that fills the room before the rest of you arrives.

This ring centres a large cushion-cut lab-grown pigeon blood ruby in vivid magenta-red within a double halo construction that is the most visually expansive ring face format available. The cushion cut — a rounded-corner square with a modified brilliant facet pattern — delivers pigeon blood ruby colour across a broad, softly-edged face that is larger in visible area than a round stone of equivalent carat weight, while the rounded corners give the colour a warmer, less architectural quality than a hard-edged square or emerald cut. Pigeon blood is the most coveted ruby colour designation: a vivid, pure, slightly blue-tinged red with maximum saturation and no brown or orange modifiers, and in cushion cut the colour is delivered with characteristic cushion brightness — a more diffuse, internally luminous quality than the step-cut flashes of an emerald cut. The double halo is the defining construction element: an inner halo of closely-set round brilliant white stones traces the cushion outline precisely, and beyond this, an outer halo of larger round brilliant white stones extends the ring face further; the two concentric rings of white brilliance create a graduated frame that makes the centre cushion ruby appear substantially larger than its physical dimensions, and the difference in stone size between inner and outer halo creates a stepped, three-dimensional depth effect that a single halo does not produce. Below the double halo mount, a split shank pavé band divides into two parallel micro pavé rails set with round brilliant white stones, extending the white stone vocabulary of the double halo across the full finger width and giving the ring a visual width at the shank that is proportional to the expansive double halo face above. The ring is open-back adjustable, fitting a range of finger sizes without resizing. At $157.50, this ring delivers cushion pigeon blood ruby colour, double halo construction, and pavé split shank band in a single piece.

Why You'll Love It

• Double halo — the most expansive ring face construction — two concentric rings of round brilliant white stones surround the cushion ruby; the inner halo traces the cushion outline closely, and the outer halo of larger stones extends the ring face further in a graduated frame; the double halo makes the centre ruby appear substantially larger than its physical size, and the difference in stone scale between the two halos creates a three-dimensional stepped depth effect
• Cushion cut for vivid pigeon blood colour with soft edges — the cushion cut’s rounded-corner square outline and modified brilliant facet pattern deliver pigeon blood ruby colour with a diffuse internal luminosity; the rounded corners give the colour a warmer, more approachable quality than a hard-edged square cut, while the large face area maximises visible vivid magenta-red saturation
• Pigeon blood — the benchmark ruby colour — pigeon blood is the most coveted ruby colour designation; vivid, pure, slightly blue-tinged red with maximum saturation and no brown or orange modifiers; in cushion cut within a double halo, the vivid magenta-red reads at ring-glance distance with immediate impact and the double white stone frame amplifies its apparent depth by contrast
• Pavé split shank proportional to the double halo face — two parallel micro pavé rails extend from the double halo mount across the full finger width; the split shank is proportionally scaled to the expansive double halo face above it, giving the complete ring a visual coherence that a plain shank beneath a large double halo does not achieve
• Open-back adjustable — fits without resizing — the open-back construction allows the ring to fit a range of finger sizes by gentle adjustment; no sizing required at purchase, no resizing required if finger size changes; the adjustable format makes this ring immediately wearable as a gift without the need for size information from the recipient
