Diamond Octagonal Halo Pendant – Fluted Sunburst Bezel with Prong Accents | 3D CAD Model for Jewelry (3DM, STL, OBJ)
*** All Files Types Include
DesignThis pendant centers a 5.00mm round brilliant stone (approximately 0.47tw) set within a bold octagonal frame that combines a deep bezel with eight decorative ball prongs positioned symmetrically around the stone. The surrounding halo is finished with a fluted, sunburst-style ray pattern radiating outward across each facet of the octagon, adding dimension and light play to the outer edge of the piece. A sturdy trapezoid bail connects the pendant to the chain, reinforced with a rounded jump ring for smooth, secure movement. The silhouette is compact and versatile, suited to both everyday wear and gifting occasions such as engagements, anniversaries, or birthdays. The design reads equally well in yellow, white, and rose gold finishes, as shown in the rendered variations.
3D ModelingThe file was constructed as a precision, manufacture-ready solid model with clean, watertight geometry suitable for both digital rendering and physical production. Full technical dimensions are included and verified within the CAD environment: overall pendant length of 12.75mm, bail height of 4.25mm, pendant width and depth of 8.00mm and 2.00mm respectively, a 5.00mm center stone seat, and a total front-to-back depth of 4.00mm. Gem and metal reporting tools were used to validate the design, confirming a single 5.00 x 5.00mm round stone at 0.47tw, along with calculated metal weights across a full range of alloys, including 9K, 10K, 14K, and 18K white gold, sterling and continuum silver, and 10K rose gold. The model is fully parametric-ready for resizing and separates cleanly into its component parts (bail and body) for production flexibility.
ManufacturingThis CAD file is optimized for real-world jewelry production and is compatible with casting, 3D printing (resin or wax), and CNC workflows. It is delivered in industry-standard formats, including 3DM, STL, and OBJ, ensuring compatibility with major jewelry design software and most rapid-prototyping or direct metal printing systems. The geometry has been checked for wall thickness, prong strength, and stone seating accuracy to support a smooth transition from digital file to finished, wearable piece in gold, silver, or platinum.
SalesThis listing is intended for jewelry designers, manufacturers, 3D printing services, and stock CAD marketplaces seeking a ready-to-produce pendant design. Buyers receive a complete, print-and-cast-ready file set suitable for commercial use, custom resizing, or direct integration into an existing product catalog. The design's clean lines and adaptable metal finishes make it a strong addition to bridal, gifting, or everyday fine jewelry collections, offering immediate value to studios and retailers looking to expand their catalog without starting a design from scratch.
