Marquise 8x6mm Bezel-Set Stud Earrings — Diamond Solitaire Earring 3D CAD Model
*** All Files Types Include
DescriptionThe Design
This listing features a pair of marquise-cut, full bezel-set solitaire stud earrings — a clean, modern take on a timeless silhouette. Each earring showcases a single marquise-shaped gemstone fully wrapped in a smooth, faceted metal bezel that tapers to a sharp point at both tips, echoing the natural elongated shape of the stone while adding structure and everyday durability. The bezel's beveled outer edge catches and reflects light around the entire perimeter of the gem, giving the piece a bright, polished presence without the visual bulk of a heavier setting. Secured with a traditional friction post and scroll (butterfly) back, the design is lightweight, comfortable for all-day wear, and equally at home as a subtle everyday accessory or a refined addition to a formal look. The design is offered ready to render in white gold, yellow gold, and rose gold, and adapts cleanly to platinum or silver as well.
The 3D Modeling
The earrings were engineered as precision, manufacture-ready solid models with fully accurate real-world proportions and wall thicknesses. Each component — the marquise bezel head, the tapered gallery, the post, and the scroll back — is modeled and organized as a separate, clean, watertight solid, allowing for easy editing, resizing, or re-purposing with different gem cuts and carat weights. Stone placement and bezel seating were verified using integrated gem-reporting tools, confirming accurate marquise gem dimensions and a combined total gem weight suited for a matched pair. Metal volume and weight were likewise calculated and verified across a full range of alloys — including 9K, 10K, 14K, and 18K white gold, 10K rose gold, and sterling silver — giving buyers reliable, ready-to-quote weight data before a single piece is cast. The native file is built in Rhino (.3dm) with clean, printable topology and is exported to universal formats including .STL and .OBJ, along with other formats available on request, making the model compatible with the vast majority of CAD, CAM, and 3D printing software used in the jewelry industry.
Manufacturing
This file is production-ready and suitable for the full range of modern jewelry manufacturing workflows. It is optimized for resin and wax 3D printing for lost-wax investment casting, as well as for direct metal 3D printing and CNC milling. Wall thickness, bezel gauge, and post/scroll proportions have all been checked to hold up structurally in casting metals of varying densities, minimizing the risk of warping, porosity, or breakage during production and polishing. The model scales cleanly for different marquise gemstone sizes and can be reproduced in 9K, 10K, 14K, or 18K white, yellow, or rose gold, platinum, or sterling silver, making it a flexible base design for manufacturers offering multiple metal and finish options to their customers.
Sales & Usage
This CAD file is ideal for jewelry designers, manufacturers, casting houses, and online jewelry retailers looking for a polished, market-ready stud earring design to add to their catalog. It suits businesses offering made-to-order or print-on-demand fine jewelry, as well as designers who want a proven, well-tested marquise bezel template to customize with alternate gemstone sizes, metal finishes, or gallery details. Delivered as a complete, multi-format package (.3dm, .STL, .OBJ, and other formats available), the file allows for an immediate move from digital model to physical sample with minimal rework, shortening turnaround time from concept to finished, sellable product.
