Love Heart Padlock Pendant – 3D CAD Jewelry DesignProduct NameLove Heart Padlock Pendant – 3D Jewelry CAD Model (Diamond Heart Cluster Design)
*** All Files Types Include
DescriptionDesign OverviewThe Love Heart Padlock Pendant is a romantic, symbolic jewelry piece that combines the timeless imagery of a padlock with the universal emblem of love, the heart. The pendant body is designed as a classic lock silhouette with a rounded shackle and a solid lock body, while the front face features a heart-shaped setting cluster containing three round brilliant diamonds surrounded by bead-like decorative accents that trace the heart's outline. The overall silhouette measures approximately 10.50mm in height, 7.00mm in width, and 4.00mm in depth (bail to lock face), making it a versatile pendant size suitable for both everyday wear and gifting occasions such as anniversaries, Valentine's Day, engagements, or promise-style jewelry. The design carries strong sentimental appeal, symbolizing a locked-in or secured bond between two people, and works beautifully across yellow gold, white gold, and rose gold finishes as demonstrated in the accompanying renders.
3D Modeling DetailsThis CAD file was constructed using industry-standard jewelry modeling software with precise, manufacture-ready geometry. The gem-set heart motif totals 3 round stones at 1.20mm x 1.20mm each, amounting to a combined gem weight of approximately 0.020 total carat weight, as verified through an integrated gem reporting tool. Full dimensional callouts are included (front and side profile views) to guide resizing or scaling for production. Metal weight calculations have also been generated across a wide range of alloys, including White Gold (9K, 10K, 14K, and 18K in various palladium and standard blends), Sterling Silver, Silver Continuum, and Rose Gold, with gram, DWT, and specific gravity values provided for cost estimation purposes. The model is delivered clean, watertight, and properly scaled, ready for rendering, prototyping, or direct production workflows. Files are typically supplied in widely compatible formats such as 3DM, OBJ, STL, and other common jewelry CAD exchange formats.
Manufacturing SuitabilityThis file is optimized for both traditional lost-wax casting and modern 3D printing production methods, including resin-based printers and wax printers commonly used in the jewelry industry. The solid, evenly distributed lock body and reinforced shackle design help ensure structural durability during casting and reduce the risk of warping or breakage in the finished piece. The heart-shaped gem setting is designed with adequate metal support around each stone seat to allow for secure prong or bead setting during the stone-setting process. The design is compatible with a wide range of precious metals, including yellow gold, white gold, rose gold, platinum, and sterling silver, giving manufacturers flexibility to produce the pendant across multiple price points and finishes.
Sales & Licensing UseThis CAD file is ideal for sale on 3D model marketplaces, jewelry design libraries, and stock content platforms catering to jewelers, designers, and manufacturers worldwide. It suits buyers seeking ready-to-produce pendant designs for retail collections, custom order fulfillment, or private label jewelry lines. The included technical documentation, such as dimensional drawings, gem specification reports, and metal weight tables, adds significant value for buyers by streamlining costing and production planning. This listing is well-suited for jewelry CAD designers, 3D printing service bureaus, casting houses, and independent jewelers looking to expand their catalog with a polished, sentimental, and market-ready pendant design.
