Diamond Halo Round Pendant – 3D CAD Jewelry DesignProduct NameRound Halo Diamond Pendant – 3D Jewelry CAD Model (0.55 ct TW, 13 Stones) | STL, OBJ, 3DM Printable File for Jewelry Manufacturing
*** All Files Types Include
DescriptionDesign OverviewThis pendant design centers on a classic round halo motif — a single round brilliant stone (5.00mm, approximately 0.47ct) held in a delicate four-prong setting, encircled by a smooth, sculpted donut-shaped frame set with twelve accent round stones (1.20mm each, approximately 0.08tw combined) for a total gem weight of roughly 0.55tw across 13 stones. The rounded, high-polish band framing the center stone gives the piece a soft, contemporary silhouette that works equally well as an everyday layering piece or a polished gift item. The fixed bail is sized for a standard chain and is proportioned to sit flush against the neckline. Overall pendant height including bail is 17.00mm, with a pendant face diameter of 11.00mm and a face thickness of 3.50mm, making this a versatile, wearable scale suited to both delicate and statement styling.
3D Modeling DetailsThe model was built as a fully manufacturable, print-ready solid using professional jewelry CAD software, with clean, watertight, non-manifold-free geometry suitable for both digital rendering and physical production. Gem seats, prong placements, and the halo channel are precisely dimensioned and proportioned to standard round stone sizing (5.00mm center, 1.20mm accents), and the file includes verified metal weight and gem weight reports for accurate costing before production. The design is provided in multiple industry-standard formats — including 3DM, STL, and OBJ — along with accompanying technical drawings showing full dimensions, bail specifications, and side-profile depth, making it easy to import into Rhino, Matrix, 3Design, ZBrush, or any major CAD/CAM and slicing software.
Manufacturing NotesThis file is ready for both traditional lost-wax casting and direct metal or resin 3D printing. It has been tested and weighted across a wide range of metal options, including 9K, 10K, 14K, and 18K white gold (standard and palladium white alloys), 10K rose gold, and .925 sterling or Continuum silver, with gram, DWT, and specific gravity values provided for each so manufacturers can quote and cost the piece accurately without additional calculation. The hollow-cored, socketed detailing on the reverse side is optimized for lightweight casting without sacrificing structural strength around the prongs and halo. The design accommodates standard gem-setting workflows and is suitable for small-batch handcrafted production as well as larger-scale manufacturing runs.
Licensing & Sales UseThis CAD file is intended for sale to jewelry designers, manufacturers, 3D printing services, and retailers seeking a ready-to-produce pendant design. Buyers receive complete source files suitable for resizing, re-gemming, metal substitution, and further customization, along with reference renders and dimensioned technical drawings to support catalog listings, quoting, and production planning. Ideal for use on jewelry stock marketplaces, print-on-demand jewelry platforms, and custom manufacturing pipelines, this file offers a clean foundation that can be adapted into engagement, anniversary, or fashion pendant collections with minimal modification.
