Lab Ruby Cushion Sugarloaf Full Diamond Pavé Feather Drop Earrings | S925 Silver Spine Barb Plume

A vivid red pyramid above a full diamond feather. The earring that makes the room go quiet when you walk in.

A large cushion sugarloaf lab-grown ruby — a square cushion stone with a smooth, pyramid-domed top surface — in vivid, deeply saturated rose-red sits in a four-prong setting above a full round brilliant diamond pavé feather drop of exceptional scale and craftsmanship. The feather is constructed with a central spine running the full length of the drop, from which approximately ten pairs of individual barb elements extend symmetrically on each side — each barb a separate, tapered silver element fully covered in round brilliant diamond pavé, the barbs graduating in length from shorter at the top to longer toward the centre and tapering again toward the pointed tip, creating the precise silhouette of a full feather. Every surface of every barb and the central spine is covered in round brilliant diamonds; the feather contains hundreds of individual diamonds across its full length, creating a drop of exceptional diamond coverage and brilliance. The cushion sugarloaf ruby’s pyramid dome catches light from above and creates a vivid red focal point of exceptional presence above the feather’s white diamond cascade. At $630, this is the ruby feather earring that earns its place as the most dramatic piece in any collection.

Why You'll Love It

• Full diamond pavé feather construction — approximately ten pairs of individual barb elements extend symmetrically from a central spine, each barb fully covered in round brilliant diamond pavé; the feather contains hundreds of individual diamonds across its full length, creating a drop of exceptional diamond coverage and brilliance that catches light along every barb simultaneously
• Anatomically precise feather silhouette — the barbs graduate in length from shorter at the top to longer toward the centre and taper again toward the pointed tip, creating the precise silhouette of a full natural feather; the anatomical precision of the feather’s construction gives the earring a sense of naturalism and movement that a stylised feather cannot achieve
• Cushion sugarloaf ruby stud — the square cushion stone’s smooth, pyramid-domed top surface creates a ruby with a deep, mirror-like colour saturation and a bold, architectural presence; the sugarloaf cut’s pyramid dome is associated with the great couture jewellery houses and gives the stud a distinctive silhouette that a conventional faceted stone cannot replicate
• Dramatic long drop format — the feather’s substantial length creates a dramatic drop that sits well below the earlobe, creating an elongating effect on the neck and a sense of movement and animation as the feather catches light from multiple angles simultaneously; the long format is among the most photographable in fine jewellery
• Guilt-free luxury — lab-grown rubies share the same optical and chemical properties as mined stones, with a significantly lower environmental footprint
