A wide-faced signet ring featuring detailed acanthus scrollwork on the shoulders. The design has a substantial presence, tapering from a maximum top width of 18.47mm down to a 5.11mm shank base. Its shoulders are deeply carved with an intricate Baroque-style floral and vine motif, providing significant surface texture and relief. The top face is a flat, unadorned plane measuring 3.21mm thick, designed for custom engraving or to be left as a high-polish surface. The shank has a low-profile, comfort-fit design with a base thickness of 1.58mm, balancing the wide top. The model is provided as a solid mesh, with weight calculations available for various precious metals, intended for direct 3D printing and casting workflows.

Production & Compatibility - Casting: The solid geometry and deep relief are well-suited for lost-wax casting. A high-resolution castable resin print from an SLA/MSLA system (e.g., Formlabs, Asiga, Phrozen) is recommended to capture the fine scrollwork detail. - CNC Milling: This model is also an excellent candidate for 3-axis or 4-axis CNC machining from a wax block, given its solid construction and lack of severe undercuts. - Mesh: The model is a solid, manifold mesh designed for production workflows.
Q: What is the size of the flat top surface available for engraving? A: The top face is approximately 18.47mm wide and features a flat, polished plane suitable for initials, monograms, or custom designs. The bezel height is 3.21mm from the shank.
Q: Is this ring solid or hollowed out? A: This is a solid-back signet ring. The model is a solid, manifold mesh, not scooped or hollowed. This construction leads to an approximate weight of 14.0g in 18K gold and 9.4g in 925 silver for a mid-range size.
Q: How does the shank width vary from top to bottom? A: The ring has a significant taper for comfort. It measures 18.47mm at its widest point across the top shoulders and tapers down to a 5.11mm width at the base of the shank.
