Heart Diamond Drop Pendant – Bezel-Set Heart Halo Necklace | 3D CAD Model (3DM, STL, OBJ + more)
*** All Files Types Include
Product Description
Design This pendant pairs a bezel-set heart-shape diamond with a sculptural open heart door-knocker loop suspended beneath it, creating a layered, two-tier heart silhouette that catches the light from every angle. The center stone is framed in a smooth bezel with a subtle notched peak at the top of the heart, and is flanked by two decorative capped pins that pierce through the setting — a small hardware-inspired detail that gives the piece a modern, sculptural edge rather than a purely classic look. Below the stone, a solid open heart ring swings freely, echoing the gem's shape and adding movement and dimension to the design. A fixed trapezoid bail connects the pendant to a cable chain, keeping the piece balanced and comfortable to wear at the neckline. The design is gender-neutral in styling and reads equally well as an everyday layering piece or a special-occasion gift, and it has been rendered and tested in yellow gold, white gold, black rhodium, and rose gold to confirm it holds its identity across finishes.
3D Modeling The pendant was built as precision jewelry CAD using industry-standard NURBS and mesh modeling workflows, with gem and metal reporting tools used throughout development to verify accuracy before export. The center stone is a heart-shape faceted diamond measuring 6.00 x 6.00 mm with an approximate weight of 0.76 carats, modeled with correct faceting geometry rather than a simplified stand-in. Overall pendant dimensions are approximately 13.00 mm wide across the outer pins, 13.50 mm tall from bail top to heart-loop base, 6.00 mm across the bail, 4.50 mm in depth, and 1.50 mm bail wall thickness — all metric, all scalable without distorting proportions. The file is fully solid, manifold, and watertight, with clean wall thicknesses suitable for both digital rendering and physical production. Included with the model are reference metal-weight calculations across common alloys — including 9K, 10K, 14K, and 18K white gold, sterling silver, and rose gold — so buyers can estimate material cost before committing to a metal. The model is delivered in native 3DM format along with STL, OBJ, and other common exchange formats, making it compatible with the major jewelry CAD packages (Rhino/Matrix, RhinoGold, 3Design, JewelCAD) as well as general-purpose 3D, rendering, and slicing software.
Manufacturing This file is production-ready and intended for real-world jewelry manufacturing, not just visualization. It is suitable for wax 3D printing followed by traditional lost-wax casting, or for direct metal 3D printing, in gold, silver, platinum, or brass. The bezel setting, bail, and heart-loop have been modeled with casting-appropriate wall thicknesses and clearances so the piece can be cast, cleaned up, polished, and stone-set using standard bench jewelry techniques. Prong tips, bezel walls, and the connecting pins are all sized to hold up through casting, finishing, and everyday wear, and the open heart-loop is solid rather than hollow for durability. The design scales cleanly for different chain gauges, stone sizes, and metal choices, making it a practical base model for a small production run, a one-off commission, or a full retail collection.
Sales This CAD file is ideal for jewelry designers, manufacturers, 3D print bureaus, and online jewelry retailers looking to add a distinctive, ready-to-produce pendant to their catalog without starting a design from scratch. It suits e-commerce product photography, jewelry configurators, custom order fulfillment, and print-on-demand casting services alike, and its modular structure (stone, bezel, pins, loop, bail) makes it straightforward to resize the gem, swap metal color, or adapt the loop shape for a personalized or private-label version. Because it is supplied as clean, native, multi-format CAD data rather than a locked render, buyers can immediately move the file into their own production pipeline — cutting design-to-market time for shops that want a fresh, sellable heart pendant design this season.
