Teardrop Lotus Round Diamond Necklace Pendant – 3D CAD ModelProduct DescriptionTeardrop Lotus Round Diamond Necklace Pendant – 3D CAD Design for Jewelry Manufacturing
*** All Files Types Include
Design OverviewThis listing presents an elegant teardrop-shaped pendant necklace featuring a round brilliant-cut diamond floating within an open, pear-shaped frame. The center stone (5.00mm, approximately 0.47ct) is held by a delicate three-prong setting suspended inside the negative space of the teardrop outline, creating a graceful dancing diamond effect that catches light and movement with every wear. A pointed apex at the top of the teardrop connects to a small jump ring and cable-link chain, giving the piece a refined, minimalist silhouette suited to both everyday wear and special occasions. The pendant measures approximately 9.50mm x 12.50mm, and the design is shown rendered in white gold, yellow gold, and rose gold finishes, demonstrating its versatility across different metal tones and customer preferences. A smaller-scale version featuring a 4.00mm accent stone (0.24ct) is also included, offering size flexibility for the same design language.3D Modeling DetailsThe model was constructed in a professional jewelry CAD environment (Rhino/Matrix-based workflow) with fully closed, watertight, manifold geometry ready for production. The file includes a native .3dm source file along with universally compatible export formats such as .STL, .OBJ, and others, ensuring compatibility with most CAD, rendering, and 3D printing software. Accurate gemstone libraries were used for the round brilliant center stones, and the Gem Reporter tool confirms precise stone specifications (round stones at 5.00mm and 4.00mm, totaling 0.71tw across both sizes shown). Metal weight calculations across multiple alloys (9K, 10K, 14K, 18K white gold, sterling silver, and rose gold variants) are included for accurate cost estimation, with the pendant alone weighing approximately 0.8–2.4 grams depending on metal choice and size. The open teardrop frame, prong setting, bail, and jump ring are all modeled to correct real-world proportions and wall thicknesses for structural integrity.Manufacturing SuitabilityThis CAD file is fully prepared for both traditional lost-wax casting and modern additive manufacturing (resin 3D printing/DLP/SLA for wax patterns, or direct metal printing). The clean topology, appropriate wall thickness, and properly modeled prongs, bail, and open frame mean the file requires minimal to no rework before printing or milling. It is suitable for producing wax patterns, silver samples, or finished pieces in gold, platinum, or silver alloys, and can be scaled or resized for custom stone sizes without loss of design integrity. The pendant and chain components are modeled separately for accurate assembly and casting workflows.Sales & Licensing UseThis file is ideal for jewelry designers, manufacturers, 3D printing services, and online CAD marketplaces looking to expand their catalog with a ready-to-produce, market-tested pendant necklace design. It suits both small-batch custom jewelers and larger production houses, and can be resold, customized, or used as a base template for stone size and metal variations. Buyers receive a production-ready, print-ready, and cast-ready design that shortens time-to-market and reduces the need for additional CAD development.
