Martini Diamond Stud Earrings — Complete Size Set 3D CAD Model (2.5mm–7.0mm)
*** All Files Types Include
Product Description
This 3D CAD design presents a classic martini-style diamond stud earring, engineered as a complete, ready-to-produce size set ranging from 2.5mm to 7.0mm in 0.5mm increments — ten full sizes covering everything from delicate everyday studs to bold statement pieces. The design features the timeless three-prong martini basket, named for its tapered, glass-like silhouette that cradles a round brilliant gemstone with minimal metal coverage, allowing maximum light return and sparkle. Each earring is paired with a secure friction-style scroll back (butterfly closure) threaded onto a straight post, a proven, comfortable wear system suited to daily use. The open, low-profile basket design keeps the stone sitting close to the earlobe while the three-claw prong setting holds the gemstone securely from below, making this style equally at home as a solitary accent or as a base for colored gemstones, moissanite, or lab-grown diamonds.
The model was constructed with precision jewelry CAD software (Rhino-based workflow) and is delivery-ready in universally compatible formats, including .3dm, .obj, .stl, and other formats commonly requested for jewelry production, rendering, and marketplace use. Every size in the set has been individually built and verified rather than simply scaled, ensuring correct prong proportions, basket depth, and post/scroll geometry at each gemstone diameter — from a 2.5mm accent stone up through a 7.0mm centerpiece. The files include clean, manifold, watertight mesh geometry suitable for both digital rendering and physical output, along with properly scaled gemstone placeholders sized to standard round brilliant cut dimensions (2.50mm through 7.00mm), so stone-setting reports and carat weight estimates for each size are already built into the file structure for immediate reference.
From a manufacturing standpoint, this design is production-tested for both traditional lost-wax casting and direct 3D printing/resin workflows, making it suitable for wax printing, RPT (rapid prototyping technology), or direct-to-metal additive manufacturing. Metal weight data has been calculated and verified across a wide range of alloys — including 9K, 10K, 14K, and 18K white gold, .925 sterling and Continuum silver, and 10K rose gold — giving manufacturers accurate gram and pennyweight estimates before production, which supports fast quoting and cost planning. The prong thickness, post diameter, and basket wall dimensions have been designed with real-world durability in mind, reducing the need for manual reinforcement or rework prior to casting, milling, or printing.
For sellers and designers, this file set offers strong commercial value as a ready-to-list product on 3D model marketplaces, jewelry CAD libraries, and print-on-demand platforms. Its broad size range means a single purchase serves multiple customer needs, from birthstone gifts to graduation presents to premium diamond studs, widening its appeal across bridal, fine jewelry, and fashion jewelry categories alike. The included technical data — gemstone specifications, total carat weight breakdowns, and metal weight tables — reduces the buyer's own R&D time, making the file attractive to independent jewelers, small ateliers, and larger manufacturing houses looking for a dependable, market-tested martini stud template they can customize, brand, and bring to production quickly.
