Spire Drop — Diamond Huggie Hoop Earrings with Textured Cone Pendant | 3D Jewelry CAD Model (3DM, OBJ, STL, STP)

Product DescriptionThe Design

The Spire Drop earring pairs a sleek, channel-set diamond huggie hoop with a bold, elongated cone-shaped pendant that tapers to a fine point. The hoop carries a single vertical row of nine round brilliant-cut diamonds per side (eighteen stones total), set flush within a rectangular channel for a clean, uninterrupted line of sparkle. Suspended from a soldered jump ring below the hinge, the cone drop is the true signature of this piece: a faceted, basket-like surface built from crossing horizontal and vertical ribs that catch light from every angle, giving the illusion of a woven or fluted lattice wrapped around a solid spike form. The contrast between the delicate, gem-set hoop and the sculptural, architectural drop makes this design equally suited to minimalist everyday wear and directional, statement-making collections. The earring closes with a secure hinged lever-back and post, sized for a comfortable, standard piercing.

The 3D Modeling

This listing includes a fully engineered, production-ready CAD file built to real-world jewelry tolerances rather than a decorative visualization only. The hoop measures approximately 12.00 mm x 5.00 mm with a 9.00 mm lever-back mechanism, and the cone pendant measures roughly 16.00 mm in length by 6.00 mm at its widest point, bringing the total drop length to approximately 30.50 mm — all fully editable and rescalable in your modeling software. Every diamond is modeled as a true 1.00 mm x 1.00 mm round stone in accurate seats, with the complete gem schedule (18 stones, approximately 0.07 total carat weight) verified using gem-reporting tools, and metal weights pre-calculated across multiple alloys including 9K, 10K, 14K, and 18K white gold, yellow gold, rose gold, and sterling silver. The mesh is clean, watertight, manifold, and free of self-intersections or flipped normals, with even wall thickness throughout the cone lattice to prevent casting failure. Files are delivered in native 3DM along with universal OBJ, STL, and additional exchange formats, compatible with Rhino, Matrix, 3Design, ZBrush, and most CAD/CAM and slicing software used in the jewelry industry.

Manufacturing

This design is built for real production, not just rendering. The model is pre-checked and optimized for both wax 3D printing (resin or wax-based DLP/SLA printers) for traditional lost-wax casting, and for direct metal 3D printing where supported. Rib spacing and wall thickness on the cone drop have been kept within safe minimums so the lattice detail prints and casts cleanly without webbing, warping, or breakage, and the diamond seats are dimensioned for standard 1.00 mm round melee, making stone-setting straightforward for bench jewelers. The file works equally well in 14K/18K yellow, white, and rose gold, sterling silver, and platinum, and can be adapted for black rhodium plating or blackened finishes as shown in the renders. Because all dimensions, gem counts, and metal weights are already documented, manufacturers and workshops can move directly from file to quote to production without re-engineering the design, saving time on prototyping and costing.

Sales & Licensing

This CAD file is offered for sale as a digital jewelry design asset for designers, manufacturers, 3D printing services, and retailers who want a ready-to-produce earring model without starting from scratch. It's well suited for private label and made-to-order jewelry lines, e-commerce catalogs needing 3D/AR-ready assets, and CAD libraries for casting houses and bridal or fine jewelry workshops. Buyers receive the complete file package (3DM, OBJ, STL, and supporting formats) along with the documented gem and metal specifications shown in this listing, ready for immediate use in quoting, prototyping, or manufacturing. As with all CAD purchases, please review the seller's specific usage license before reselling the design itself, reproducing it in competing digital marketplaces, or using it in mass-market retail without appropriate rights — the file is intended for creating and selling finished jewelry pieces made from the design.
