Classic Round Solitaire Engagement Ring – Fluted Crown Basket Setting | 3D Jewelry CAD Model (11mm, 3.11ct Round Brilliant)
*** All Files Types Include
Design OverviewThis engagement ring design features a round brilliant cut center stone held in a distinctive fluted crown basket setting, where a ring of vertical scalloped prongs wraps continuously around the stone's girdle, creating a sculptural, sunburst-like halo effect without the use of traditional side stones. The center gem — modeled at approximately 9.40mm x 9.40mm, equivalent to a 3.11 carat round brilliant — sits elevated above a smooth, comfort-rounded cathedral shank that tapers cleanly into the basket for a timeless, elegant silhouette. The open, fluted gallery beneath the stone adds airiness and allows maximum light entry for brilliance, while the plain polished band keeps the overall look versatile and wearable for daily use. The design is well suited for engagement rings, anniversary rings, promise rings, or statement solitaires, and renders beautifully in yellow gold, rose gold, white gold, and platinum finishes.
3D Modeling DetailsThe model was built and finalized in professional jewelry CAD software with clean, manufacture-ready topology, accurate wall thicknesses, and properly closed, watertight geometry suitable for both rendering and production. Overall dimensions measure approximately 11.00mm x 11.00mm across the head with an 8.00mm gallery height and a 2.00–3.00mm shank profile, keeping proportions realistic and comfortable for finger wear. The gemstone is modeled as a fully faceted round brilliant cut, separately assignable for accurate light performance in renders. The file package includes the native CAD source along with universally compatible export formats — 3DM, STL, OBJ, and other common mesh formats on request — making the model ready for CNC milling, resin/wax 3D printing, or direct reference use in rendering engines such as KeyShot, Blender, or Rhino/Matrix.
Manufacturing InformationThis design is fully 3D-printable and production-tested for real-world jewelry manufacturing via lost-wax casting or direct metal printing. Calculated metal weights are provided across a range of alloys — including 9K, 10K, 14K, and 18K white gold, sterling silver, silver continuum, and 10K rose gold — with example castings ranging from roughly 4.1g to 6.2g depending on the alloy chosen, giving buyers accurate cost-estimation data before production. The prong and gallery wall thicknesses have been checked for structural durability to securely hold the center stone under everyday wear. The ring is easily resizable in CAD prior to casting, and the center stone setting can be adapted to accommodate lab-grown or natural diamonds, moissanite, or other round gemstones of comparable dimensions.
Licensing & UsageThis 3D CAD file is offered for commercial use by jewelry designers, manufacturers, casting houses, 3D printing services, and online jewelry retailers looking to expand their solitaire engagement ring catalog without starting from scratch. Buyers receive full production-ready files suitable for prototyping, sample casting, and full-scale manufacturing, as well as high-resolution render-ready geometry for use in product photography, e-commerce listings, and marketing visuals. The design can be resized, recolored in different metal finishes, or paired with alternative gemstone cuts and carat weights to suit a brand's specific product line, making it a versatile, ready-to-sell addition to any fine jewelry collection.
