Heart-in-Heart Diamond Stud Earrings — Door-Knocker Style 3D CAD Model
*** All Files Types Include
Description
This design pairs a bezel-set heart-shaped diamond with an open, heart-contoured hoop suspended beneath it, creating a layered heart-in-heart silhouette with the sculptural drop of a classic door-knocker earring. Each earring is built around a 6.00 x 6.00 mm heart-cut center stone framed in a smooth bezel, with the lower heart-shaped loop echoing the same silhouette in a bold, polished band. The result is a piece that reads as romantic and directional at once — wearable for everyday polish yet striking enough for a statement look. The model is shown finished in both platinum/white gold and 18K yellow gold, with a screw-back post assembly (barrel and ball) as well as a standard friction/butterfly-back post option, so the file can be produced as a secure screw-back stud or a conventional push-back stud depending on customer preference. Total gemstone weight across the pair is 1.53 ct (two heart-cut diamonds), with the design fully proportioned for a 13.00 mm total drop and a 4.50 mm post depth, making it comfortable for the earlobe while keeping the heart motif clearly legible.
3D Modeling
The CAD file is modeled with clean, manufacture-ready topology and delivered in multiple formats for maximum compatibility — native 3DM (Rhino), OBJ, STL, and additional formats on request — so it can be opened directly in Rhino/Matrix, 3Design, ZBrush, or any standard 3D printing and CAM pipeline. All components — the heart bezel, the diamond gemstone, the hoop/loop element, the post, and the back (screw barrel or butterfly clutch) — are modeled and grouped as separate, cleanly named solids, making it easy to swap stones, resize the shank/post, or adjust proportions without rebuilding the design. The gemstone data is pre-calculated using industry-standard gem-reporting tools (heart cut, 6.00 x 6.00 mm, 2 stones, 1.53 ct total weight), and the mesh has been checked for watertight, manifold, non-intersecting geometry so it is print-ready straight out of the box. A metal-weight reference table is included, covering estimated gram and DWT weights across common alloys (9K, 10K, 14K, and 18K white gold, sterling silver, and 10K rose gold, among others), giving buyers an immediate sense of finished piece weight and material cost before committing to production.
Manufacturing
This file is built for real-world jewelry production, whether by 3D wax/resin printing followed by lost-wax casting, or by direct metal 3D printing. It is compatible with 14K, 18K, and platinum in white, yellow, or rose tones, as well as sterling silver, and scales cleanly to other carat purities without loss of detail in the heart contours or bezel setting. The bezel is dimensioned to accept a 6.00 mm heart-cut diamond or lab-grown diamond (or can be resized for moissanite, sapphire, or other heart-cut gemstones), and both post styles included in the file — secure screw-back and standard friction back — mean manufacturers can produce whichever closure their market prefers without remodeling. Wall thicknesses, bezel walls, and the hoop profile have been kept within safe casting and printing tolerances, reducing the risk of warping, porosity, or breakage during casting, polishing, or stone setting, and the file is equally suited to small-batch bench production or larger CAM-driven manufacturing runs.
Sales
This listing is intended for jewelry designers, manufacturers, casting houses, 3D printing services, and online jewelry retailers looking for a ready-to-produce, on-trend earring design without the cost or turnaround time of custom modeling. The included files (3DM, OBJ, STL, and other formats) allow instant integration into existing production workflows, e-commerce product visualizations, or customer-facing 3D configurators. Buyers receive full production-ready geometry along with reference renders (white gold and yellow gold), technical dimension views, and gem/metal weight data to support accurate pricing and listing descriptions on their own storefronts. The design is offered under a standard commercial-use license for manufacturing and resale of physical pieces produced from the file; redistribution or resale of the digital CAD files themselves is not permitted. Download is instant upon purchase, and the file is ready to send directly to print, cast, or CAM software with no additional cleanup required.
