Lab Pigeon Blood Ruby Oval Mixed-Cut Diamond Cluster Pendant Necklace | S925 Silver Pear Marquise Floral Halo

The rarest red, surrounded by ten large diamonds. The pendant that looks like it belongs in a museum — and on your collarbone.

An oversized oval-cut lab-grown pigeon blood ruby in vivid, deeply saturated rose-red sits in a four-prong setting within a mixed-cut large diamond cluster halo — approximately ten large individually-set diamonds in pear and marquise cuts arranged in a floral or starburst formation around the ruby: two pear-cut diamonds above (tips pointing upward, creating a natural bail transition), two pear-cut diamonds on each side (tips pointing outward), two pear-cut diamonds below (tips pointing downward), and marquise-cut diamonds at the diagonal positions, their elongated silhouettes filling the spaces between the pear clusters. The large scale of each individual diamond — each stone substantial enough to be a statement piece on its own — and the mixed-cut variety of the cluster create a halo of exceptional visual complexity and presence; this is not a micro-pavé halo but a cluster of large, individually-faceted stones, each catching light independently and creating a pendant that appears to change as it moves. Pigeon blood is the most prized colour classification in the ruby world, describing a vivid, deeply saturated red with a slight blue undertone that gives the stone an almost luminous quality in any light. Suspended on a polished S925 silver cable chain. At $319.50, this is the ruby pendant that earns its place as the most significant piece in any collection.

Why You'll Love It

• Large mixed-cut diamond cluster halo — approximately ten large pear and marquise diamonds individually set in a floral cluster formation create a halo of exceptional visual complexity; the large scale of each individual stone and the mixed-cut variety of the cluster give the pendant a presence and movement that a micro-pavé halo cannot replicate; each stone catches light independently and the pendant appears to change as it moves
• Pear diamond bail transition — two pear-cut diamonds above the ruby with tips pointing upward create a natural, organic transition from the pendant to the chain; the pear diamonds’ teardrop silhouette gives the pendant a graceful upward movement that draws the eye toward the chain and creates a composition of exceptional visual flow
• Pigeon blood ruby centrepiece — pigeon blood is the most prized colour classification in the ruby world, describing a vivid, deeply saturated red with a slight blue undertone that gives the stone an almost luminous quality; the oval cut’s elongated silhouette maximises the ruby’s colour saturation and creates a commanding focal point within the diamond cluster
• Floral starburst composition — the radial arrangement of pear and marquise diamonds around the ruby creates a floral or starburst silhouette that is immediately distinctive and associated with the great couture jewellery houses; the composition’s organic, botanical quality gives the pendant a sense of life and movement
• Guilt-free luxury — lab-grown pigeon blood rubies share the same optical and chemical properties as mined stones, with a significantly lower environmental footprint
