Marquise Diamond Sunburst Halo Stud Earrings — 3D CAD Model (10x5mm Center Stone)
*** All Files Types Include
Product DescriptionThe Design
This listing presents a pair of marquise-cut stud earrings built around a bold, fluted sunburst halo. Each earring centers a 10mm x 5mm marquise stone held securely by four rounded prongs — two at the points and two along the widest curve of the stone — so the full length and brilliance of the marquise cut stay unobstructed. Framing the stone is a ribbed, fan-like halo that radiates outward in fine vertical flutes, echoing the pointed silhouette of the marquise shape and adding dimension, texture, and extra sparkle without competing with the center stone. The design is finished with a standard friction-back post and butterfly clutch for comfortable, everyday wear, and it scales elegantly whether set with a colorless diamond, a sapphire, an emerald, or another fancy-cut gem of matching proportions. The model renders cleanly in classic white gold and warm yellow gold, and the fluted halo can be plated or finished in white, yellow, rose gold, or black rhodium to suit a wide range of collections, from minimalist everyday studs to a more statement-making cocktail earring.
The 3D Modeling
The earring pair was engineered in professional jewelry CAD software using industry-standard plugins for gemstone and metal reporting, ensuring every dimension is production-accurate rather than aesthetic guesswork. The center stones are modeled as true 10.00mm x 5.00mm marquise cuts, with a built-in gem report confirming a total gem weight of approximately 1.63 carats across the pair (2 stones). Full technical dimensioning is included, showing an overall earring height of 13.00mm, a stone length of 10.00mm and width of 5.00mm, a halo outer width of 7.50mm, and a compact side profile of 4.50mm total depth with a 1.50mm setting thickness — all optimized to sit close and comfortably to the earlobe. A metal weight report is provided across common alloys, including 9K, 10K, 14K, and 18K white gold, 10K rose gold, and .925 sterling silver, giving buyers immediate insight into finished piece weight and material cost before production. The native file is fully solid, watertight, and clean-topology, ready for direct export and further customization such as stone size swaps, halo styling, or post/backing changes.
Manufacturing
This CAD model is production-ready and suitable for both traditional lost-wax casting and modern digital manufacturing workflows. Files are provided in native 3DM format along with universally compatible export formats such as OBJ, STL, and other formats, making the design usable in Rhino, Matrix, 3DS Max, ZBrush, and most casting and 3D printing software. The geometry is built with correct wall thicknesses, secure prong engineering, and a properly seated gallery, so the piece is suitable for wax printing, resin printing for lost-wax casting, or direct metal 3D printing in gold, silver, platinum, or brass. The fluted halo and marquise setting have been checked for printability and structural integrity, reducing the risk of casting defects, thin walls, or broken prongs during production. Jewelry manufacturers, casting houses, and independent goldsmiths can use this file as-is or resize and re-gem it to fit different center stone dimensions, ring/earring sizing requirements, or metal specifications.
Sales & Licensing
This 3D CAD file is intended for jewelry designers, manufacturers, 3D printing services, e-commerce jewelry sellers, and hobbyist makers looking for a polished, ready-to-produce earring design without starting from scratch. It is well suited for stock 3D model marketplaces, print-on-demand jewelry platforms, and B2B CAD libraries, and it can be sold as a single design file, bundled into a broader stud earring or halo-collection package, or offered with multiple export formats and gemstone/metal variant renders included. Buyers receive a technically accurate, sales-ready asset complete with dimensioned drawings, gem and metal reports, and clean production geometry — reducing the buyer's own CAD workload and enabling faster turnaround from purchase to finished, sellable jewelry. Please review the specific marketplace's licensing terms at the time of listing (personal use, commercial production use, resale/redistribution rights, and exclusivity) to match the appropriate license tier to your customer base.
