Four Prong Diamond Stud Earrings – Round Brilliant Solitaire, 10-Size Set (2.5mm–7.0mm) | 3D Printable CAD Model for Jewelry (STL, OBJ, 3DM)
*** All Files Types Include
Design OverviewThis listing features a timeless four-prong round brilliant stud earring, one of the most requested and best-selling designs in fine jewelry. The classic claw-prong basket setting is engineered to hold a round brilliant cut center stone securely while maximizing light exposure for maximum brilliance and sparkle. The file set includes ten proportionally scaled sizes, from a delicate 2.5mm stud to a bold 7.0mm statement piece, giving manufacturers and designers a complete, ready-to-produce size run for round stones between roughly 0.06ct and 1.29ct total weight. The friction-back post and clutch (butterfly back) closure is modeled as a functional, symmetrical component, and the basket, prongs, and gallery are all balanced for everyday wearability, secure stone retention, and a comfortable fit against the earlobe. The design is gender-neutral and versatile enough for bridal, everyday, gifting, and birthstone collections, and it renders equally well in white metal, yellow gold, and rose gold, as well as with colored gemstones such as topaz, morganite, amethyst, and emerald in place of diamond.
3D Modeling DetailsThe model was built using professional jewelry CAD software with manufacturing-grade precision, and every size in the ten-piece set has been individually verified for proportion, prong height, and stone-to-basket ratio rather than simply scaled uniformly. The files include clean, watertight, manifold geometry appropriate for both digital rendering and physical output, with dimensioned technical drawings provided for reference (post length, basket width, and overall height are clearly labeled for each size). Gem reports and metal weight calculations are included for each size across a range of common alloys — 9K, 10K, 14K, and 18K white gold, yellow gold, rose gold, platinum, and sterling silver — giving buyers accurate estimated gram weights, DWT, and specific gravity data before production. The package is delivered in industry-standard formats including STL, OBJ, and native 3DM (Rhino), along with commonly requested exports, making the files compatible with most jewelry CAD, rendering, and slicing software.
Manufacturing CompatibilityThis design is fully prepared for real-world jewelry production and is suitable for both traditional lost-wax casting and modern digital manufacturing workflows. The mesh is optimized for resin 3D printing on wax printers or standard SLA/DLP printers used for investment casting, as well as for direct metal 3D printing where available. Wall thickness, prong dimensions, and post/clutch tolerances have been considered with real manufacturing constraints in mind, reducing the need for rework before casting. The included metal weight tables allow manufacturers to quickly quote material costs across a wide range of alloys and karats without additional software calculations, streamlining production planning for both single custom orders and batch manufacturing runs.
Sales & LicensingThis file set is ideal for jewelry designers, manufacturers, CAD studios, 3D printing services, and online jewelry retailers looking to expand their stud earring catalog with a proven, universally appealing design. Because it includes ten complete sizes with supporting technical documentation, it offers strong value as a ready-to-sell or ready-to-produce product line rather than a single SKU. The files are well suited for use on 3D model marketplaces, print-on-demand jewelry platforms, and direct-to-consumer customization tools where customers select a stone size or metal type. Buyers are receiving a complete, production-tested digital asset that can be resized, remixed with different gemstones or metals, and brought to market quickly, making it a practical addition to any jewelry design library or e-commerce catalog.
