Open Marquise Pendant CAD Model | Plain Metal, Knife-Edge Frame

Description

The open marquise pendant CAD model features an elongated open oval frame with two curved arms meeting at upper and lower pointed tips. The frame cross-section transitions from a broad flat face along the mid-body to a knife-edge profile at both pointed tips — creating subtle dimensional depth and light-catching surface movement across a clean minimalist silhouette. The upper tip pinches directly into an integrated bail connector, maintaining uninterrupted visual continuity from chain to frame with no separate bail component required.

Zero stones, zero assembly, zero setting labor. The open marquise pendant CAD model is a single-piece casting structure with a wax CNC reference weight of 0.18g (manufacturing reference only) — confirming ultra-minimal metal consumption per unit. The slim 4.67mm depth profile and high-polish geometry suit layering necklace retail positioning and everyday fine jewelry collections. Compatible with 10K–22K gold (YG/WG/RG), Platinum (PLAT/PLAT RU), and 925 Silver across all retail price tiers.

Production Analysis — Open Marquise Pendant CAD Model

• Casting Readiness: Very High — open frame geometry with integrated bail; cleanest possible single-piece casting structure with no assembly, no setting, no secondary components
• Printability: Very High — DLP/SLA resin compatible; simple open loop with consistent wall thickness; excellent surface quality potential for high-polish finishing
• Stone Setting Difficulty: None — plain metal design; zero setting labor per unit
• Polishing Difficulty: Low-Medium — broad flat frame faces polish efficiently; knife-edge tip transitions and inner frame edge require hand tool access for full mirror finish quality
• Mass Production Suitability: Very High — ultra-low metal volume, zero setting labor, and single-piece casting make this the most production-efficient structure in the pendant CAD category
• Repair Friendliness: Excellent — no prongs, no stones, no assembly; repair limited to surface re-polishing or minor frame reshaping only
• Recommended Metals: 14K Gold (YG/WG/RG), 18K Gold (YG/WG/RG), 925 Silver, Platinum (PLAT/PLAT RU)

Market Fit Analysis

• US Market Fit: Very Strong — open marquise frame suits minimalist everyday jewelry, layering necklace, and demi-fine jewelry segments with broad US retail reach across Silver to gold alloy price tiers
• Etsy Compatibility: Very High — clean geometric open frame is a proven Etsy search category; flat frame face supports laser engraving personalization as a boutique seller upsell option
• TikTok Jewelry Potential: High — simple bold silhouette performs well in necklace layering and styling content; high-polish metal surface catches light effectively in close-up video
• Pinterest Visual Appeal: High — open marquise pendant suits minimalist jewelry, everyday gold jewelry, and layering necklace discovery boards with strong sustained search volume
• Commercial Flexibility: Very Strong — single CAD file supports multi-alloy SKU expansion from 925 Silver to 22K gold with no design modification; personalization engraving option adds retail customization tier without structural change

FAQ

Q: What is the per-unit production cost advantage of the open marquise pendant CAD model compared to a standard pavé pendant structure at the same alloy?
A: The open marquise frame uses approximately 2.64g in 14K yellow gold versus 5–7g for a typical pavé pendant — roughly 50–60% less metal per unit. Combined with zero stone setting labor, the total per-unit production cost is substantially lower, making this model well suited for entry-level fine jewelry retail price points and high-volume batch production runs.

Q: Does the knife-edge cross-section transition at the pointed tips create any structural fragility risk in 925 Silver production?
A: The knife-edge taper at the tips is a surface profile transition, not a structural thinning of the frame wall. At standard production wall thickness, the frame maintains adequate rigidity in 925 Silver. The tips are the primary polish-care zones but do not present meaningful fragility risk under normal retail wear conditions.

Q: Can the flat face of the open marquise frame support laser engraving for a personalized retail product line without modifying the CAD file?
A: Yes. The broad flat mid-body face on both sides of the frame provides sufficient surface area for standard laser engraving of initials, dates, or short text. No CAD modification is required — engraving is applied post-casting as a standard jewelry finishing step, enabling a personalized retail variant without additional tooling or file adjustment.
