Diamond Triangle Curved Halo Pendant — 3D Jewelry CAD Model
*** All Files Types Include
Description
This pendant is built around a soft, organic take on the classic triangle silhouette — three gently curved, hand-sculpted bands that loop and overlap to form an open halo around a central round brilliant stone. Rather than sharp geometric corners, the outline flows with rounded, wave-like edges that catch light along their length, giving the piece a molten, hand-forged look despite its precise construction. The round stone sits slightly offset within the frame, held securely by four rounded prongs, and the whole pendant hangs from a curved, tapered bail that continues the same fluid design language. It's a versatile everyday piece that reads as delicate on its own and bold enough to layer, suited equally to bridal, fashion, and gifting collections.
The model was built as a fully manufacturable jewelry CAD file, modeled with clean, closed, watertight geometry and accurate wall thicknesses throughout the shank, prongs, and bail. The center stone is set as a standard round brilliant at 3.50 x 3.50mm (approximately 0.16ct), with the prong tips properly sized and positioned for secure stone retention. Overall pendant dimensions are 8.00 x 8.00mm with a bail opening of 3.50mm, and the file has been checked in multiple metal densities (14K/18K white, yellow, and rose gold, .925 sterling silver, and platinum) to confirm gram weight is realistic and production-ready across metal choices, as shown in the included render pack. Files are supplied native plus exported to industry-standard formats (3DM, STL, OBJ, and others), so they open cleanly in the major CAD, sculpting, and slicing packages used across the jewelry industry.
Because the geometry is solid, manifold, and correctly scaled, this file is ready to go straight into production: it can be 3D printed for lost-wax casting, milled, or used to generate a wax/resin master directly, and it is compatible with common in-house or service-bureau workflows for rings, pendants, and similar cast jewelry. The design has been proofed for wall thickness and prong strength so it holds up through casting and stone-setting without the rework that's common with un-vetted files, and it can be scaled or adapted to different stone sizes, metals, or chain-drop lengths with minimal adjustment.
This listing is intended for jewelry designers, manufacturers, CAD studios, and 3D print/casting services looking for a ready-to-use, sale-ready pendant design rather than a decorative-only render. It's well suited to jewelry brands wanting a fast addition to a diamond pendant line, small studios building out a catalog without modeling from scratch, and print-on-demand or custom-jewelry sellers who need dependable, pre-checked geometry. Buyers receive the full source and export files along with reference renders and technical views, making it easy to preview, customize, and put into production quickly.
