Heart Halo Pearl Necklace — Floating Pearl & Diamond Heart Frame Pendant | 3D CAD Jewelry Design File (3DM, STL, OBJ)
*** All Files Types Include
Description
This design captures a modern, romantic take on the classic heart pendant: a round pearl (or pearl-cut gemstone) sits suspended in the open center of a sleek heart-shaped halo, held in place by a bezel frame studded with a graduated row of round bezel dots along the sides. The lower curve of the heart is finished with a hand-set line of pavé round diamonds that trace the bottom point of the silhouette, giving the piece a soft sparkle without overwhelming the pearl's natural luster. A double jump-ring bail sits at the top of each lobe, allowing the pendant to swing freely and catch the light from every angle. The design reads equally well in polished yellow gold, warm rose gold, or crisp white gold/silver, making it a versatile everyday piece as well as a gift-ready option for anniversaries, Valentine's Day, bridal jewelry, or push-present style gifting.
The file was built in professional jewelry CAD software with full attention to real-world manufacturability. The pendant measures approximately 10.00mm wide by 9.50mm tall at the heart frame, with a 6.00mm bail opening sized for standard chain links, keeping the piece delicate and wearable rather than oversized. The center stone seat is modeled for a round cabochon/pearl of roughly 6–7mm in diameter, and the lower pavé row is set with 8 round melee stones (approx. 1.00mm each, ~0.030 total carat weight as configured), each cut with fully faceted CAD geometry rather than simplified placeholder gems. The model is clean, manifold, and organized in layers/groups (metal shell, prongs/bezel dots, gem seats, bail) so stones, metal, and settings can be edited, re-sized, or swapped independently without rebuilding the design from scratch.
Every solid in the file is closed, watertight, and print-ready straight out of the box, making it suitable for direct resin 3D printing (SLA/DLP/LCD) for lost-wax investment casting in gold or silver, as well as for direct metal printing workflows. A metal weight reference table is included, covering common casting alloys such as 9K, 10K, 14K, and 18K white gold, .925 sterling silver, silver continuum, and 10K rose gold, giving manufacturers a fast starting point for costing and quoting before final wax/print calibration. Wall thicknesses, bezel heights, and gem-seat depths have been kept within standard casting tolerances, and the open heart silhouette has been reinforced at the join points to reduce the risk of warping or breakage during casting, polishing, or stone-setting.
This listing includes the native 3DM file along with exported STL and OBJ formats, plus additional common exchange formats on request, so the design can be dropped straight into most CAD, rendering, and 3D printing pipelines used by jewelry manufacturers, custom jewelers, prototyping services, and independent designers. It's well suited for print-on-demand and made-to-order jewelry businesses, catalog and lookbook renders, physical sample production, or as a base design to customize with alternate gemstones, metal finishes, or chain lengths. As with all digital design files, please review the specific usage license provided at purchase (personal, commercial, or extended commercial use) before reproducing, reselling, or mass-manufacturing the design.
