Description
Round Diamond Open Heart Pendant 3D Model Overview
This Graduated Halo Open Heart Pendant CAD model traces an open heart outline with 28 shared-prong round diamonds, tapering from smaller stones near the top to larger stones along the lower curve. The open frame center reduces metal density while maintaining structural rigidity across the outline.
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 graduated fringe structure supports SKU expansion into multiple metal and stone-size variations from a single production-ready CAD file.
