The concentric circle pearl pendant CAD model is structured around three nested circular frames — a smooth outer ring, a plain inner ring, and a lower crescent arc surface set with three rows of micro pavé round diamonds. The 8.5 mm pearl seat is positioned at center, floating within the inner ring with open clearance on all sides. Silhouette geometry is circular and symmetrical from the front face, with a projected rear depth of 9.60 mm (0.378") to accommodate the pearl dome profile. The pavé-set bail integrates four round diamonds along the tube, maintaining visual continuity with the crescent arc below.

This concentric circle pearl pendant CAD model is manufacturing-ready across 14K, 18K Gold (YG/WG/RG), Platinum, and 925 Silver. Complete metal weight data is provided for all 13 alloy variants, enabling direct production costing without CAD modification. The nested ring geometry supports clean sprue placement and straightforward casting separation. Wax CNC reference weight is 0.75 g (manufacturing use only).
