Princess Diamonds Couple Band Rings – 3D CAD ModelProduct Listing DescriptionPrincess Diamonds Couple Band Rings – 3D CAD Design (His & Hers Matching Wedding Bands)
*** All Files Types Include
DescriptionDesign OverviewThis listing features a matching couple's wedding band set engineered with a bold, architectural aesthetic. Each ring combines a textured brick-pattern center panel with a twisted rope-style inner rail and a beaded (milgrain-style) outer rail, creating a rich, multi-layered profile. Princess-cut gemstones are channel-set at intervals across the brick pattern, adding sparkle without disrupting the geometric rhythm of the design. The set includes two band widths — a bold 7mm men's band and a slender 4mm women's band — allowing couples to coordinate a shared design language while wearing proportions suited to each hand. The model renders cleanly in white gold, yellow gold, and rose gold, and displays equally well with diamond, sapphire, or emerald gemstone variations, making it a versatile base file for a wide range of catalog offerings.
3D Modeling DetailsThe design was modeled with precision CAD jewelry software and is fully parametric-ready, with clean, manufacturable geometry and no non-manifold errors. The file includes exact digital specifications: a women's band width of 4.00mm and a men's band width of 7.00mm, with princess-cut gemstone seats sized at 1.50 x 1.50mm, accommodating 24 stones per set at approximately 0.51 total carat weight (calculated using standard diamond density references). Metal weight has been calculated across a full range of alloys, including 9K, 10K, 14K, and 18K white gold, sterling silver, silver continuum, and 10K rose gold, giving buyers accurate gram and pennyweight (DWT) estimates before production. Files are delivered in industry-standard formats — 3DM, STL, and OBJ — with additional formats available on request, ensuring compatibility with major CAD platforms such as Rhino, Matrix, and 3Design, as well as most 3D printing and casting workflows.
Manufacturing NotesThe model is optimized for direct use in lost-wax casting, resin 3D printing, and CNC milling workflows. Wall thicknesses, prong seats, and gemstone channels have been designed to hold their shape through the casting process while maintaining structural durability for everyday wear. The brick-textured surface and beaded rail are modeled with sufficient depth and clean edges to reproduce sharply in both wax printing and direct metal casting, minimizing post-casting cleanup. The gemstone settings are sized to standard princess-cut proportions, allowing manufacturers to substitute lab-grown or natural diamonds, sapphires, emeralds, or cubic zirconia without modification to the seat geometry.
Sales & LicensingThis CAD file is ideal for jewelry manufacturers, custom jewelers, 3D printing bureaus, and online jewelry retailers looking to expand their bridal and couple's ring catalog with a distinctive, ready-to-produce design. Buyers receive a print-ready, manufacture-ready digital file suitable for immediate integration into production pipelines or online 3D model marketplaces. The design's dual-width, dual-texture construction makes it well suited for matching set promotions, anniversary collections, and customizable metal/gemstone bridal offerings.
