Description
Open Heart Pendant STL File Overview
This Uniform Halo Open Heart Pendant CAD model sets 28 evenly sized round diamonds in a shared-prong row along a smooth open heart frame, finished with a plain loop bail. The consistent stone sizing reduces sourcing complexity relative to graduated or cluster halo designs.
The file is production-ready across 10K, 14K, and 18K yellow, white, and rose gold, 22K yellow gold, platinum, and 925 silver, making it suitable for CAD marketplaces and B2B factory quoting. Its uniform-stone structure supports SKU expansion into multiple metal finishes from a single production-ready CAD file.
