Double Ring Frame Pearl Pendant CAD Model | STL 3DM JCD

Description

This double ring frame pearl pendant CAD model is built as a single-body casting geometry integrating three structural elements: a full 360° dual-row pavé circular ring frame, a vertical pavé cross bar piercing the ring at top and bottom, and an open center cavity seating a 10 mm floating pearl. The ring frame carries 28 round brilliants (1.6 mm) in a dual-row shared prong layout running the full ring circumference. The vertical cross bar carries 16 round brilliants (1.3 mm) in a linear single-row layout across the upper bail section and lower decorative tail — forming a continuous diamond column through the ring center. No jump ring or separate bail component is required; the bail loop is cast integral to the top of the vertical bar.

The double ring frame pearl pendant CAD model delivers a geometrically distinctive cross-in-circle silhouette with two independent high-density diamond zones intersecting at a single cast structure. The open ring cavity allows the 10 mm pearl to float visibly inside the frame without a prong or bezel enclosure — maximizing pearl surface visibility from all viewing angles. The geometry is DLP/SLA printable with clean wall thickness throughout the ring frame and cross bar sections. Full multi-metal weight data covers 10K through 22K gold in YG/WG/RG, Platinum PLAT/PLAT RU, and 925 Silver — supporting broad multi-metal retail catalog production from a single casting-ready file.

The open 10 mm center seat accommodates Tahitian black, South Sea golden, South Sea white, and freshwater round pearls from a single production file. Multi-pearl-color SKU expansion requires no CAD modification.

Production Analysis

• Casting Readiness: High — fully integrated single-body geometry; ring frame, cross bar, and bail loop cast as one piece; no post-cast assembly steps required
• Stone Setting Difficulty: High — 28-stone full 360° dual-row pavé ring requires precision angular spacing and experienced setter; 16-stone linear cross bar setting is straightforward; ring-to-bar junction stone seats require careful alignment at four intersection points
• Polishing Accessibility: Medium — outer ring convex surface and bar faces fully accessible; inner ring cavity behind pearl seat and bar-to-ring junction interior require flex-shaft tool access
• Mass Production Suitability: Medium-High — single-body casting eliminates assembly labor; 44-stone setting throughput is the primary production rate constraint; geometry scales well for DLP/SLA wax printing batches
• Repair Friendliness: High — open ring frame provides unobstructed access to all prong positions; pearl is not encased and can be removed and replaced without structural disassembly
• Recommended Metals: 14K Gold (YG/WG/RG), 18K Gold (YG/WG/RG), Platinum (PLAT/PLAT RU), 925 Silver

Market Fit Analysis

• US Market Fit: Strong — geometric open circle pearl pendant is a commercially recognizable contemporary fine jewelry format; 0.548 CT dual-zone pavé specification supports competitive US retail price positioning in the fine jewelry segment
• Etsy Compatibility: High — architectural cross-in-circle silhouette differentiates from standard pearl pendant formats; geometric structure appeals to contemporary and modern fine jewelry buyers
• TikTok Jewelry Potential: Very High — full 360° dual-row pavé ring frame produces exceptional all-angle sparkle in video lighting; geometric cross-in-circle silhouette reads instantly in close-up short-form content
• Pinterest Visual Appeal: High — bold circular pavé frame with floating pearl and vertical cross bar produces a strong graphic composition; rose gold + golden South Sea pearl and white gold + Tahitian black pearl colorways both photograph with high visual contrast
• Commercial Flexibility: High — open 10 mm pearl seat supports multiple pearl type and color variants from a single casting file; single-body construction simplifies multi-metal SKU production; no redesign required for alloy or pearl color changes

Double Ring Frame Pearl Pendant CAD Model — FAQ

Q: Is the vertical cross bar structurally integrated with the ring frame in the casting file, or is it a separate component?
A: The vertical cross bar, ring frame, and bail loop are all integrated into a single-body casting geometry. No post-cast assembly or soldering is required. The cross bar pierces the ring frame at top and bottom as one unified cast structure — simplifying production workflow and eliminating assembly labor cost.

Q: How is the 10 mm pearl secured inside the open ring frame cavity during production?
A: The pearl seats inside the open ring cavity and is typically secured with a pearl peg post-setting, glued into a drilled pearl seat at the base of the ring frame interior. This is a standard production method for open-frame floating pearl pendants and requires no modification to the casting file geometry.

Q: Does the dual-row ring frame pavé layout maintain consistent stone spacing across the full 360° circumference?
A: Yes. The CAD model places dual-row stone seats at consistent angular intervals across the full ring circumference, with the 1.6 mm stone size calibrated to the ring frame diameter for uniform coverage. The cross bar junction zones at 12 o’clock and 6 o’clock are accounted for in the seat layout — no stone seats conflict with the bar intersection points.
