13mm Pearl Pendant Micro Pave Diamond CAD Casting File

Description

Introduction

This CAD model is engineered for manufacturing workshops producing pearl pendant jewelry at scale. The design integrates a 13mm spherical pearl seat with a micro pave diamond crown and a secondary diamond-set circular bail connector. The geometric architecture is developed to support direct casting production without structural modification. This 3D model is suitable for Tahitian pearl, South Sea pearl, and freshwater pearl mounting applications across 10K, 14K, 18K gold, and platinum alloy workflows.

The pendant structure separates into two functional zones: the upper bail assembly with a pavé-set ring connector, and the lower swirl-arm crown that wraps the pearl sphere. This two-zone approach allows casting workshops to evaluate each section independently for wall thickness compliance and stone-setting tolerance before committing to full production runs.

Manufacturing Benefits

• Casting-Ready Geometry: The metal framework is optimized for lost-wax casting with clean sprue attachment points and adequate escape hole placement for hollow sections.
• Printable Structure: Wax CNC weight at 0.23g confirms the model is suitable for DLP and SLA resin printing prior to casting. Wall geometry supports standard 3D wax printing tolerances.
• Micro Pave Stone Setting Optimized: Stone seat diameters and bead prong spacing are pre-engineered for consistent round brilliant placement without manual adjustment.
• Pearl Seat Architecture: The open bowl structure accommodates standard 13mm round pearls and allows post-casting pearl adhesion or mechanical setting as required by the workshop workflow.
• Multi-Alloy Scalable: Metal weight data is pre-calculated across 10K, 14K, 18K gold alloys and platinum, enabling direct cost estimation before production.

Stone Setting Structure

The micro pave diamond layout is distributed across two structural zones. The circular bail ring carries the primary stone concentration using shared bead prong micro pave, arranged in a closed circular formation. The lower swirl arm features a graduated diagonal line setting that wraps partially around the pearl seat circumference.

All stone seats are pre-cut to precise tolerances matching their respective round brilliant diameters. The bead prong micro pave method is applied throughout, using a consistent prong height profile that minimizes post-casting cleanup. Stone groupings are segmented by size zone to allow selective setting based on available stone inventory — workshops may substitute adjacent size grades without structural alteration to the CAD file.

Production Specifications

CAD Workflow Compatibility

The 3DM file is fully editable in Rhino 3D and compatible with RhinoGold and Matrix Gold plugin environments. The JCD file supports direct import into JewelCAD Pro for workshops operating on legacy JewelCAD production pipelines. The STL export is high-resolution and ready for slicing software without remeshing. All geometry passes standard manifold checks required for clean STL output.

For casting preparation, the file can be imported directly into casting tree assembly software. No Boolean repair operations are required. Stone placement guides remain visible as reference geometry in the 3DM file and can be toggled off prior to final STL export.

Manufacturing Notes

The swirl arm crown section contains the thinnest wall geometry in this model. Before committing to full casting runs, confirm wall thickness compliance at the arm tip — minimum recommended wall is 0.6mm for gold alloys and 0.5mm for platinum. The bail ring connector is solid-bodied and carries no hollow section risk.

When scaling the model for pearl size variation (e.g., 11mm or 12mm pearls), scale uniformly and re-verify stone seat diameters after scaling, as stone sizes do not scale proportionally to pearl size in production practice. The metal crown and bail assembly may require independent resizing in that case. Post-casting, the pearl seat should be cleaned and polished prior to pearl adhesion or pin setting.

FAQ

Q: Is this 13mm pearl pendant micro pave diamond CAD casting file ready for direct production?
A: Yes. The geometry is casting-ready and has been validated for lost-wax workflow. No structural repair is required before printing or casting.

Q: What pearl types are compatible with the 13mm seat?
A: The open bowl seat is designed for 13mm round pearls and is compatible with South Sea, Tahitian, and high-grade freshwater round pearls.

Q: Can the model be adapted for a different pearl size?
A: Yes. The 3DM file is fully editable. Uniform scaling is recommended, with post-scale verification of stone seat tolerances.

Q: What diamond setting method is used?
A: Micro pave bead prong setting throughout. All stone seats are pre-cut and sized to match the specified round brilliant diameters in the stone layout.

Q: Is the file compatible with JewelCAD production environments?
A: Yes. A JCD file is included alongside the 3DM and STL formats for direct use in JewelCAD Pro pipelines.

Q: Which metal alloys have pre-calculated weight data?
A: Weight data is available for 10K, 14K, 18K gold (yellow, white, rose), 22K yellow gold, platinum, and 925 silver — covering all standard casting alloys used in US and EU manufacturing.
