9mm Pearl Drop Earrings Micro Pavé Diamond CAD 3DM File

Description

Production-Ready Pearl Drop Earring CAD Model for Jewelry Manufacturing

This 9mm Pearl Drop Earrings Micro Pavé Diamond CAD 3DM File is engineered for jewelry manufacturers, casting workshops, and B2B CAD model buyers who require a fully verified, casting-ready earring design with complex stone setting architecture. The model has been developed in JewelCAD Pro and exported as a 3DM file compatible with Rhino and standard STL-based 3D printing workflows.

The earring follows a three-section vertical drop structure. The top section is an oval-shaped micro pavé stud post. The middle section is a spherical cluster node featuring a center diamond surrounded by a halo of round brilliant stones. The bottom section is a crown prong mount engineered to hold a 9mm round pearl. All three sections are geometrically optimized for lost-wax casting with clean wall thickness and precise prong geometry throughout.

Jewelry manufacturers searching for a pearl drop earring CAD model with micro pavé diamond setting will find this asset directly usable in production without additional geometry correction or reconstruction.

Manufacturing Benefits

This CAD model delivers measurable production workflow advantages for jewelry casting houses and manufacturing studios.

• Casting-ready geometry: All prong structures, wall thicknesses, and stone seat depths are optimized for lost-wax casting. No geometry repair required before printing.
• Multi-metal weight pre-calculated: Metal weight data is embedded across all major alloy types including yellow gold (10K–22K), white gold, rose gold, silver 925, and platinum — eliminating manual recalculation for different production orders.
• Printable STL output: The model can be exported directly to STL for resin or wax 3D printing, compatible with standard jewelry printing hardware.
• Modular three-tier structure: Each section (stud, ball node, pearl mount) can be isolated and modified independently for derivative designs or custom orders.
• Pearl mount compatibility: The crown prong base is designed to accept 9mm round pearls, with prong height and opening geometry calibrated for post-casting pearl setting.

Stone Setting Structure

The earring CAD model incorporates 118 round brilliant diamonds distributed across five stone size groups to achieve a graduated micro pavé and cluster setting effect.

• Stone shape: Round Brilliant Cut (all groups)
• Setting style: Micro Pavé (top stud section) + Cluster Setting (middle ball node) + Open Prong Crown (bottom pearl mount)
• Total stone count: 118 stones per earring
• Total diamond weight: 1.148 CT per earring

Stone size distribution per earring:

• 28 stones — 1.0 mm diameter
• 8 stones — 1.05 mm diameter
• 16 stones — 1.1 mm diameter
• 22 stones — 1.15 mm diameter
• 44 stones — 1.7 mm diameter

Prong geometry is reinforced at the cluster node section where larger 1.7mm stones are set. Micro pavé seats on the oval stud section are precision-spaced to minimize metal surface exposure while maintaining structural integrity under casting shrinkage. The crown prong structure at the base uses open-set round prongs to allow pearl mounting after casting and polishing.

Production Specifications

CAD Workflow Compatibility

This 9mm pearl drop earring CAD model is built on a JewelCAD Pro workflow and delivers broad compatibility with professional jewelry manufacturing pipelines.

• JewelCAD Pro: Native design environment. Full parametric data intact.
• Rhino 3D: 3DM file opens natively in Rhino 6, 7, and 8. Full geometry accessible for modification, scaling, or component extraction.
• STL Export: Model can be exported to STL for direct use with resin printers (Formlabs, SprintRay, Asiga) or wax printers used in investment casting workflows.
• MatrixGold / RhinoGold: 3DM geometry compatible for import and modification.
• Standard Lost-Wax Casting Pipeline: Geometry tolerances meet production requirements for investment casting at standard jewelry workshop temperatures and flask sizes.

No additional file conversion or geometry cleanup is required for standard manufacturing workflows. The model arrives production-ready from the 3DM source file.

Manufacturing Notes

This micro pavé diamond pearl drop earring CAD model is structured to support direct production entry across multiple manufacturing scenarios. The following notes apply to casting workshop preparation and production scaling.

• Scaling: The model supports proportional scaling in Rhino or JewelCAD without structural failure. Stone seat positions auto-adjust with geometry-aware scaling workflows. Manual stone seat verification is recommended after any scaling above 110%.
• Wall thickness: All metal walls are calibrated above 0.6mm minimum for casting integrity. No thin-wall failures identified in pre-export geometry checks.
• Prong geometry: Cluster ball prongs are 0.5mm tip-width, suitable for casting in 14K and 18K alloys. Platinum casting requires prong tip review due to higher shrinkage rate.
• Pearl mount assembly: The crown prong base is designed for post-casting pearl assembly. Prong tips should be bent inward manually after pearl insertion. Pearl hole drilling is not required for standard flat-base pearl mounting.
• Sprue attachment: Recommended sprue attachment point is the earring post base. The three-tier vertical structure is suitable for tree casting in standard production batches.
• Production batching: Wax CNC weight of 1.03g per earring supports efficient tree arrangement for batch casting of 10–30 pairs per flask depending on flask size.

Jewelry CAD models of this complexity — featuring a 118-stone micro pavé distribution across graduated stone sizes with an integrated pearl mount — are typically used in high-margin bridal, formal, and luxury wholesale production lines. The 3DM file format ensures that downstream manufacturers can adapt the model to client-specific metal alloy requirements without sourcing new geometry.

Frequently Asked Questions

Is this 9mm pearl drop earring CAD model casting-ready?

Yes. The 3DM file is fully casting-ready. Wall thicknesses, prong geometry, and stone seat depths are pre-optimized for lost-wax investment casting. No geometry correction is required before printing or casting.

What file formats are included?

The primary file is a 3DM file compatible with Rhino and JewelCAD. STL export is supported directly from the 3DM source for 3D printing and casting workflows.

Can this earring CAD model be resized for different pearl sizes?

Yes. The model supports proportional scaling in Rhino. For pearl sizes other than 9mm, the crown prong base diameter should be scaled accordingly and stone seat positions verified after scaling.

Which CAD software is compatible with this model?

The 3DM file is compatible with Rhino 6, 7, and 8, JewelCAD Pro, MatrixGold, and RhinoGold. STL export supports all major jewelry 3D printing systems including Formlabs, Asiga, and SprintRay platforms.

How many diamonds are in this earring CAD model?

Each earring contains 118 round brilliant stones across five size groups (1.0mm to 1.7mm diameter), with a total diamond weight of 1.148 CT per earring.

Is metal weight data available for different alloys?

Yes. Metal weight calculations are pre-embedded in the JewelCAD file for 10K, 14K, 18K, and 22K yellow gold; 10K, 14K, and 18K white gold; 10K, 14K, and 18K rose gold; silver 925; and platinum. This eliminates manual weight estimation for production quoting.

Is this model suitable for wax CNC machining?

Yes. The wax CNC model weight is 1.03g per earring. The geometry is compatible with standard wax milling machines used in jewelry production. CNC toolpath generation is supported via standard STL import.

Can I modify the stone setting layout in this 3DM file?

Yes. The 3DM file allows individual stone group modification in Rhino or JewelCAD. Stone count, spacing, and size can be adjusted for custom production orders or derivative designs.
