Octagon Coin Star Pendant with Round Diamond – 3D CAD Model for Jewelry
*** All Files Types Include
Product Description
DesignThis pendant combines a bold octagonal coin silhouette with a radiant compass-star motif at its center, creating a striking geometric statement piece with a vintage-medallion feel. A single round brilliant-cut stone, set in a scalloped prong bezel, sits at the heart of a four-point star that stretches to each corner of the octagon. The alternating polished and diagonally textured facets around the border add contrast and dimension, giving the surface a dynamic, light-catching quality from every angle. A sturdy fixed bail completes the design, making it wearable as a pendant on a chain of the customer's choice. The overall look is minimal yet distinctive — equally suited to everyday wear or as a refined gift piece — and the design translates well across gender-neutral and unisex jewelry collections.
3D ModelingThe file was built as a native, manufacture-ready jewelry CAD model with clean, watertight geometry and accurate real-world scale. Center stone specifications are a 5.00mm x 5.00mm round brilliant diamond (approximately 0.47 total carat weight), fully documented with a gem report. The pendant measures 12.00mm x 12.00mm across the coin face with a 4.00mm depth, and the bail measures 5.00mm tall with a 2.00mm inner opening to fit standard chains. Metal weight references are included for multiple alloys — 9K, 10K, 14K, and 18K white gold, 10K rose gold, and .925 sterling silver/Continuum silver — giving buyers accurate gram and DWT estimates before casting. The model is delivered with clean, closed-mesh topology and printable wall thicknesses, verified through render passes in multiple finishes (polished yellow gold, white gold, rose gold, and black rhodium/gunmetal) to confirm surface quality and detail resolution.
ManufacturingThis design is fully compatible with modern jewelry production workflows, including direct wax or resin 3D printing for lost-wax casting, as well as CNC milling. The file is suitable for production in gold (9K–18K, yellow, white, or rose), sterling silver, platinum, and other standard jewelry alloys, and it can be scaled up or down while maintaining proportional stone seating and prong integrity. The gem-set area is modeled with functional prongs sized to standard round stone dimensions, allowing manufacturers to substitute lab-grown or natural diamonds, moissanite, cubic zirconia, or other round-cut gemstones of comparable millimeter size. The textured border and star facets are optimized to hold detail through casting without excessive wax cleanup, and the design has been checked for shrinkage and finishing tolerances typical of fine jewelry manufacturing.
Sales & LicensingThis 3D CAD file is offered for commercial use by jewelry designers, manufacturers, casting houses, and 3D printing services, and is provided in industry-standard formats — including 3DM, STL, and OBJ — with other formats available on request (such as STEP or 3DS depending on platform requirements). It is ideal for buyers seeking a ready-to-produce pendant design for retail lines, custom orders, or print-on-demand jewelry services, eliminating the need for modeling from scratch. Please refer to the individual marketplace listing for specific licensing terms regarding resale, exclusivity, and print rights. For questions about customization, alternate stone sizes, or metal finishes prior to purchase, buyers are encouraged to contact the designer directly through the platform's messaging system.
