Oval Gemstone Sea Turtle Pendant — 3D Jewelry CAD Design File (3DM, STL, OBJ, Print-Ready)
*** All Files Types Include
Oval Gem Turtle Pendant is a ready-to-manufacture 3D jewelry model of a stylized sea turtle set with a single oval center stone. Designed for jewelers, casting houses, 3D printing studios, and online jewelry brands, this file combines a nature-inspired silhouette with clean, production-accurate geometry so it can move straight from digital file to finished piece with minimal rework.
The Design. The pendant depicts a solitaire oval gemstone held at its center by four sturdy prongs, framed by a turtle's head, shell outline, and four flippers rendered in a crisp criss-cross (basket-weave) texture that gives the metal surface depth and sparkle without competing with the stone. A matching textured bail sits above a rounded jump ring, allowing the pendant to hang naturally and rotate freely on a chain. The default gemstone is an oval cut measuring 7.00 x 5.00 mm (approximately 0.66 ct as modeled), though the setting can be resized to accommodate other oval stone dimensions. Overall pendant height is approximately 10.5–15.5 mm depending on bail inclusion, with a width of about 9.00 mm, making it a versatile everyday-wear scale. The design has been rendered and tested in yellow gold, white gold/silver, and rose gold finishes, and reads equally well as a fine jewelry piece or a beach/ocean-themed lifestyle pendant.
The 3D Modeling. This file was built using professional jewelry CAD workflows (Rhino-based modeling with jewelry plugins), with construction history that includes verified gem sizing and metal weight reporting — visible in the included reference screenshots showing gem specification (Oval, 7.00 x 5.00 mm, 0.66 tw) and comparative metal weight tables across 9K, 10K, 14K, and 18K white gold, sterling silver, and rose gold alloys. The mesh geometry is clean, watertight (manifold), and free of self-intersections or flipped normals, which means it is ready for both rendering and physical output without additional repair work. The model is delivered with properly scaled real-world millimeter dimensions, a centered pivot/origin for easy alignment in casting or CAM software, and separated components (main body, bail, prong setting) where applicable so gemstone size or metal thickness can be adjusted by a competent CAD user if needed.
Manufacturing. The file is optimized for the full range of standard jewelry production methods: direct 3D wax or resin printing for lost-wax casting, direct metal casting patterns, CNC milling, and additive metal printing (SLM/DMLS). It is compatible with common precious metal casting alloys — 9K, 10K, 14K, and 18K white, yellow, and rose gold, sterling silver, and platinum — with reference gram and pennyweight (DWT) estimates provided per alloy to help with cost planning and quoting. The prong setting is sized for standard oval gemstone dimensions and can be adapted for lab-grown or natural diamonds, cubic zirconia, moissanite, or colored gemstones such as aquamarine or topaz. Wall thicknesses and prong dimensions follow standard jewelry manufacturing tolerances, minimizing casting porosity risk and breakage during stone setting and polishing.
Sales & Licensing. This CAD file is intended for commercial use by jewelry manufacturers, custom jewelry designers, 3D printing service bureaus, and online marketplaces looking to expand a nature/ocean-themed or birthstone pendant collection without starting a design from scratch. It suits sellers targeting gift, beach/resort, and animal-lovers' jewelry niches, and can be offered as-is or customized with alternate gemstone sizes, birthstone colors, or engraving on the reverse. Files are typically supplied in native 3DM format alongside universal STL and OBJ exports for maximum compatibility across CAD, sculpting, and printing software. Buyers should confirm their own resale/production rights per the marketplace's licensing terms at time of purchase.
