Royal Pear-Cut Cluster Drop Earrings – Production-Ready Jewelry CAD Design
*** All Files Types Include
Product DescriptionThis premium 3D CAD model features a sophisticated pair of cluster-style drop earrings, centered around a majestic pear-shaped gemstone. Surrounded by a tiered halo of brilliant-round accents, the design blends classic Victorian elegance with modern precision. This file is engineered specifically for professional jewelry manufacturing, ensuring that wall thicknesses, prong tolerances, and stone seats are optimized for high-quality casting in precious metals.
File Formats Included: .3DM (Rhino Native), .STL (High-Poly Mesh for Printing), .OBJ (Standard 3D), .STEP (CAD Interchange).
Total Gemstone Count: 2 Pear Center Stones, 40+ Round Brilliant Accents (Variable by size).
Dimensions: Approximately 15mm x 10mm (Adjustable in 3DM).
Estimated Metal Weight: ~4.5g (14K Gold) / ~6.2g (Platinum).
About the DesignThe Royal Pear-Cut Cluster design is inspired by the timeless teardrop silhouette, often associated with royalty and vintage glamour. The focal point is a pair of crisp, pear-shaped center stones (recommended for Sapphire, Emerald, or Diamond) held by secure V-prong tips to protect the delicate points. The surrounding cluster is meticulously arranged to maximize light return, creating a shimmer effect that extends the visual surface area of the center stone. The drop mechanism is engineered for fluid movement, allowing the earrings to catch light from every angle when worn.
About the 3D ModelingThis model was developed using industry-standard NURBS-based software (Rhino/MatrixGold) to ensure absolute mathematical precision. Unlike standard 3D assets, this model features clean topology and is completely manifold (water-tight), making it ready for immediate 3D printing without further repair. The .3DM file retains the original construction geometry, allowing designers to easily scale the piece or adjust prong heights. Each gemstone seat is cut with a standard 10% overlap to ensure the stones sit flush and secure within the metal setting.
About ManufacturingEngineered with the Bench Jeweler in mind, this file accounts for all real-world manufacturing constraints. We have maintained a minimum wall thickness of 0.8mm and a prong diameter of 0.7mm to allow for material loss during the polishing and finishing phases. The STL files are exported at high resolution to eliminate faceting on curved surfaces during the 3D printing or wax-growing process. Whether you are using a Formlabs, EnvisionTEC, or Solidscape printer, this model is optimized for a clean burnout and a high-yield casting result in gold, silver, or platinum.
About SalesThis 3D CAD model is offered with a Royalty-Free license, making it a highly profitable asset for jewelry brands, independent goldsmiths, and 3D printing enthusiasts. Upon purchase, you have the right to manufacture and sell physical versions of this design indefinitely. It is an ideal addition to your digital catalog for bespoke client presentations or for building out a ready-to-wear collection. By purchasing this production-ready file, you save hours of design and testing time, moving straight from digital concept to physical luxury.
