Art Sparkle Diamond Stud Earrings — 3D CAD Model (Cross-Star Design)
*** All Files Types Include
Design Overview
The Art Sparkle Diamond Stud Earrings feature a bold, four-pointed cross-star silhouette that transforms a simple diamond stud into a striking architectural statement. At the heart of each earring sits a round brilliant-cut center stone, held securely by a delicate six-prong basket setting. Radiating outward from the center are four sculpted, dagger-like facets that taper to sharp points, creating a dynamic pinwheel or compass-rose effect that catches and reflects light from every angle. The design balances geometric precision with organic curvature — the concave, faceted surfaces of each arm are polished to mirror-bright finish, giving the piece a faceted, gem-like quality even in the metalwork itself. Overall earring dimensions measure 8.50mm x 8.50mm, with a 3.40mm center gem seat, making it a versatile, wearable size suited to both everyday elegance and statement occasions. The earrings are finished with a classic decorative scroll (butterfly-style) friction back and a 2.00mm diameter post, ensuring secure, comfortable wear.
3D Modeling Details
This file was modeled with precision jewelry CAD software to production-ready standards, fully prong-set with accurately proportioned round gemstones (2 stones, approx. 0.30 total carat weight at 3.40mm x 3.40mm each, per the included Gem Reporter output). The model includes clean, manifold, watertight geometry suitable for direct 3D printing, resin casting, and CNC milling, with properly defined prongs, undercuts, and a fully modeled scroll back and post assembly. Metal weight calculations are provided across a wide range of alloys — including 9K, 10K, 14K, and 18K white gold, sterling silver, and rose/yellow gold options — giving buyers accurate reference data for costing and quoting before production. The package includes native format files (.3dm) along with universally compatible export formats such as .STL and .OBJ, making the design accessible for Rhino, Matrix, 3Design, and most major CAD/CAM and slicing software. Wireframe, shaded, and rendered perspective views are included to verify topology and proportion accuracy prior to purchase.
Manufacturing Notes
This design is optimized for real-world jewelry production, including wax 3D printing, direct metal casting, and lost-wax investment casting workflows. The prong structure and gem seats are dimensionally accurate to standard round brilliant cut stone sizing, allowing for reliable stone-setting during finishing. The model is compatible with a full range of precious metals, including white, yellow, and rose gold (9K–18K), platinum, and sterling silver, as reflected in the included metal weight chart. The scroll-back closure and post are integrated into the model as a single connected assembly, reducing post-production labor and ensuring consistent alignment during casting and polishing. This file is well-suited for manufacturers, custom jewelers, and small-batch producers looking to bring a distinctive, ready-to-cast earring design into their catalog without additional CAD development time.
Sales & Licensing
Ideal for jewelry designers, manufacturers, 3D printing services, and online jewelry retailers, this CAD file offers a ready-to-use, professionally modeled asset for immediate integration into production pipelines or digital catalogs. Buyers receive multiple file formats to support cross-platform compatibility, along with reference renders and technical dimension sheets for accurate marketing, quoting, and quality control. This listing is well suited for stock 3D model marketplaces, jewelry design libraries, and print-on-demand jewelry platforms, offering a fresh, distinctive design that stands apart from conventional stud earring templates.
