This elegant engagement-ring CAD model features a 1.53 CT round-cut gemstone or diamond secured in a classic four-prong setting. The sculpted shoulders gently pinch and divide as they approach the center head, creating a graceful bow-inspired profile while keeping the overall design clean and timeless.

A supportive V-shaped basket and horizontal gallery rail hold the center stone securely while allowing light to enter from multiple directions. The open construction also provides convenient access for stone setting, cleaning, polishing, and finishing.

This production-ready jewelry model is suitable for classic solitaire engagement rings, minimalist bridal collections, custom gemstone jewelry, resin or wax 3D printing, casting, and professional manufacturing.
