Interlocking Double Heart Pendant CAD | Casting Ready

Description

This interlocking double heart pendant CAD model features two open ribbon hearts joined in a flowing asymmetric curve, accented by a bezel-set diamond trail along the upper heart. The smooth ribbon geometry supports a casting ready double heart pendant build with no fine undercuts to clean up.

The compact 13.17 mm (0.52″) frame and open structure keep metal usage low across all 13 alloy options, from 10K to 22K gold, platinum, and 925 silver. The two prong-set accent stones can be substituted with colored gemstones for birthstone or personalized SKU variations.

The 3D model places four 1 mm bezel-set diamonds along the upper heart curve and two 2.4 mm prong-set accent stones at the lower heart points, totaling 0.12 CT. Bezel and prong settings are positioned for straightforward stone-setting access across production runs.
