Project: 10th anniversary five-stone ring Metal: 18ct yellow gold Style: Victorian-inspired, open gallery, elegant heirloom piece Target size: to be confirmed before final CAD lock 1. Overall concept Create a refined five-stone ring with a slightly graduated layout, inspired by Victorian proportions but engineered with a modern open gallery for maximum light under the stones. The ring must feel romantic, architectural, and timeless, with all symbolic elements integrated subtly into the structure. 2. Dimensions • Top width: 6.8–7.6 mm, depending on final stone sizes. • Shoulder width: 2.3–2.6 mm tapering into the head. • Shank width at base: 1.9–2.2 mm. • Shank thickness at base: 1.4–1.7 mm after finishing. • Gallery height: 4.8–6.0 mm. • Total ring height: approx. 6.5–8.0 mm. 3. Stone layout • Five stones in a gentle graduated line. • Centre stone: 100%. • Inner side stones: 80–85% of centre. • Outer side stones: 65–75% of centre. • Keep spacing tight and balanced, but leave enough opening for light return. 4. Setting and structure • Use slim, secure claw prongs. • Prong thickness: 0.75–0.90 mm at the tip. • Keep the crown visually open. • Open gallery beneath all stones for light. • Include hidden structural support so the setting remains durable. • Avoid heavy bezels or enclosed stone seats. 5. Symbolic detailing • Integrate a discreet serif or calligraphic M into the top arch of the gallery. • Add a soft ondine wave motif in the undergallery to reference the sea. • Use Venetian Gothic palazzo-window tracery on the shoulders, with pointed arches and subtle quatrefoil or trefoil forms. • Keep all symbolic details shallow, elegant, and balanced. 6. Detail and finish • Visible engraving depth: approx. 0.2–0.4 mm. • Maintain at least 0.8–1.0 mm metal thickness around cut-outs. • Finish the exterior in high-polish yellow gold. • Keep the overall look refined, romantic, and light. 7. Manufacturing notes • Model in CAD before casting. • Confirm stone seat angles and pavilion clearance. • Ensure the ring can be resized slightly without damaging the gallery motifs. • Preserve comfort, structural integrity, and clean polish access. 8. CAD instruction summary Create a castable 18ct yellow gold five-stone anniversary ring with an open gallery, slim claws, slightly graduated stones, a hidden M in the top arch, a soft ondine wave undergallery, and Venetian palazzo-style shoulder tracery. Prioritise elegance, light performance, durability, and a discreet heirloom finish. If useful, I can next make this into a final jeweller-ready version with exact wording stripped down even further, or a matching prompt for a render tool so you can see the concept visually before CAD.
