Flower Branch Diamond Pendant — Pear-Cut Gemstone Tulip Bud Necklace | 3D CAD Model for Jewelry (3DM, STL, OBJ)
*** All Files Types Include
Design
This pendant reimagines a blooming tulip as a piece of fine jewelry. A pear-cut center gemstone forms the bud, cradled by two sweeping, sculpted petals that curve outward and are lined with a graduated row of pavé round diamonds along their inner edges. The petals meet at a small round bead detail before flowing down into a slender, gently curved stem that mimics an organic branch. A single round brilliant diamond is set part-way down the stem, echoing a bud or leaf breaking off the main flower, and the piece finishes in a smooth tapering point at the base. A classic V-bail sits at the top for a chain or cord. The silhouette is asymmetrical and free-flowing rather than symmetrical and rigid, giving the design a natural, botanical movement. Renders show the piece in rose gold with an emerald-green/paraiba-style center stone, as well as yellow gold and white gold variations, all photographed on fine cable chains — the model is intended to be easily recolored into any metal and stone combination a buyer prefers.
3D Modeling
The pendant was engineered as a precision, manufacture-ready jewelry CAD file using Rhino-based gemstone/jewelry-CAD tooling (Matrix/RhinoGold workflow), with construction history showing separated, cleanly organized solids for the bail, petal shells, stem, prongs, and bead/ball accents so each component can be edited independently. The gem-setting data is fully specified: a pear-cut center stone at 7.00 x 5.00 mm (~0.65 ct), one 3.00 x 3.00 mm round accent (~0.10 ct), four 1.40 x 1.40 mm rounds (~0.021 ctw), four 1.20 x 1.20 mm rounds (~0.026 ctw), and four 1.00 x 1.00 mm rounds (~0.015 ctw) — 12 stones total at roughly 0.81 total carat weight, all captured in an included gem report. Overall dimensions measure approximately 17.00 mm in length, 8.50 mm across the widest point of the petals, 5.00 mm across the bail, and 1.25–4.50 mm in depth/thickness through the profile, with full front, side, and perspective dimensioned drawings provided for reference. Metal weight has been calculated across common alloys (9K–18K white, yellow, and rose gold, and sterling silver), giving buyers an immediate sense of finished piece weight and cost before production. The mesh is clean, watertight, and free of self-intersections, making it reliable for downstream conversion and simulation.
Manufacturing
The model is delivered fully prepared for jewelry production. It is 3D-print-ready for both resin/DLP printers (for direct investment casting in wax-like resin) and traditional wax printers, and it also converts cleanly to STL and OBJ for CNC milling, rapid prototyping, or use in other CAD/CAM jewelry software. Wall thicknesses, prong dimensions, and stone seats have been built to realistic, castable tolerances so the piece can go from screen to sprue with minimal rework by a bench jeweler or casting house. It is suitable for casting in gold (10K, 14K, 18K in yellow, white, or rose), sterling silver, platinum, or brass/vermeil production runs, and the separated stone-seat geometry supports accurate prong or pavé setting of natural, lab-grown, or simulant gemstones in the specified sizes. The design scales proportionally if a larger or smaller finished pendant is required, though stone sizes should be re-verified after significant scaling.
Sales
This listing includes the native 3D CAD file along with exported STL and OBJ formats, the gem specification report, metal weight chart, and dimensioned technical drawings shown in the preview images, plus the polished marketing renders for reference. The file is sold for commercial use: buyers — jewelry designers, manufacturers, casting houses, 3D printing services, and independent jewelers — are welcome to produce, customize, and sell physical pieces made from this design. Resale, redistribution, or sharing of the digital CAD file itself (as-is or repackaged) is not permitted. The open, editable construction makes it simple to swap the center stone shape or size, change metal color, or adjust diamond accents to create your own variations of this piece, making it a versatile addition to a bridal, nature-inspired, or fashion jewelry collection.
