Cushion-Cut Diamond Celtic Knot Flower Pendant — 3D Jewelry CAD Model (3DM, STL, OBJ)
*** All Files Types Include
Design Overview
This pendant design centers around a bold 7mm x 7mm cushion-cut gemstone held in a four-prong setting, surrounded by an openwork frame built from interlacing Celtic-inspired knotwork arcs that curve outward into four elongated, marquise-like petals. Each petal is accented with a pair of small round bezel-set stones near its base, adding sparkle and continuity between the negative space and the central gem, for a total gem count of nine stones and a combined gem weight of approximately 1.83 carats in the reference build. A sculpted, high-polish bail with a smooth looped eye sits atop the design, sized to comfortably accommodate a standard cable or box chain. The overall silhouette measures roughly 18mm x 18mm for the pendant head, giving it a wearable, everyday-elegant scale that reads clearly whether photographed in white metal, yellow metal, or set with colored center stones such as sapphire or emerald in place of diamond.
3D Modeling Details
The design was modeled and finalized in Rhino/Matrix-based jewelry CAD workflow, with construction verified through dimension call-outs, a Gem Reporter breakdown of stone shapes, sizes, and counts, and a Metal Weights table calculated across multiple common alloys (white gold in 9K, 10K, 14K, and 18K in both palladium-white and rhodium-white variants, yellow and rose gold options, and sterling silver/continuum silver). The mesh is clean, watertight, and manifold, with properly hollowed prongs, bezels, and bail geometry ready for shelling adjustments if needed. The file set is intended to be delivered in native 3DM format along with universally compatible STL and OBJ exports, making the model accessible for CAD editing, further customization, or direct use in production pipelines without additional repair work.
Manufacturing Notes
This model is built to jewelry-industry tolerances and is fully 3D-printable for lost-wax casting, resin 3D printing, or direct metal (DMLS/SLM) production. The knotwork bands and prong structures maintain consistent wall thickness suitable for casting stability, and the stone seats are dimensioned to standard cushion and round brilliant sizing so that lab-grown, natural, or simulant stones of matching measurements can be set without modification. The design is compatible with standard bench-setting techniques (prong and bezel) and can be scaled up or down proportionally for pendant, charm, or matching earring adaptations. Metal weight tables included with the source files give manufacturers an immediate reference for costing across gold karats and silver alloys before a single wax is printed.
Sales & Licensing
This CAD file is offered for commercial use by jewelry designers, manufacturers, casting houses, and 3D print services looking to add a distinctive, nature-and-knotwork-inspired pendant to their catalog without starting a design from scratch. It suits retailers wanting a ready-to-produce SKU, as well as CAD artists seeking a well-constructed base model to adapt into rings, earrings, or bracelet charms. Buyers receive multi-format files (3DM, STL, OBJ) compatible with major jewelry CAD software and slicers, along with reference renders showing the design in white and yellow gold with diamond, sapphire, and emerald center-stone options to support marketing and customer-facing previews.
