Open Crescent Pearl Pendant CAD Model | Diamond Arc STL

Description

This open crescent pearl pendant CAD model is built on an asymmetric bypass frame forming a near-complete open circle. The left arc carries 8 graduated round diamonds (1.7mm–2.7mm) in a shared prong curved layout. The right arm sweeps into a smooth bypass tail, anchored by a compact decorative bail. An open cradle pearl seat positions the 8.5mm pearl at center, creating a distinct floating visual profile with strong silhouette differentiation.

The single-cast open frame geometry delivers low casting complexity and high polishing accessibility. The jewelry CAD model is production-ready across 10K–22K gold, platinum, and 925 silver. Open cradle construction supports pearl variation without structural redesign, making this STL file suitable for scalable production and multi-SKU retail strategies.
