The design is centered on a round brilliant-cut solitaire, held in a four-prong basket setting. This primary stone is elevated above the shank by a cathedral mounting, where the ring's shoulders sweep upward to flank and support the central stone's gallery. This architectural feature provides both structural integrity and a graceful transition from the band to the focal point. The shoulders themselves are a key design element, each featuring two parallel channels that run from the gallery junction down to the midpoint of the shank. These channels are precisely sized for small, round accent stones, creating four distinct lines of gems along the top of the ring.
The shank has a consistent width from its base to where the shoulders begin their ascent, maintaining a half-round or comfort-fit profile on the interior and a slightly domed exterior surface with a high-polish finish. The geometry of the prongs is classic, with a gentle taper towards the tips to minimize metal visibility while ensuring a secure grip on the center stone's girdle. The under-bezel is an openwork construction, which is a critical feature for maximizing light return through the pavilion facets of the main gem. This digital model is offered as a watertight manifold mesh, ensuring compatibility with standard SLA/DLP 3D printers for direct casting in castable resins. The channel walls are modeled with sufficient thickness to allow for clean casting and precise stone setting by a jeweler.

Production & Compatibility The model is constructed as a watertight manifold mesh, suitable for high-resolution 3D printing on SLA, DLP, and MSLA systems using castable resins. It is designed for standard lost-wax investment casting workflows. The channel walls and prongs are modeled with adequate thickness for a successful casting and to provide a secure foundation for professional gemstone setting.
Q: Can the four-prong setting accommodate a different stone shape, like a cushion cut? A: This model is designed specifically for a round brilliant-cut center stone. Adapting the four-prong basket for a square or cushion shape would require significant modification of the prongs and gallery in a CAD program.
Q: Is the cathedral setting considered high-profile? A: Yes, the cathedral setting elevates the central round stone significantly above the finger, creating a high-profile silhouette. This design maximizes the center stone's visibility and light exposure, which is characteristic of this style.
Q: What is the benefit of the channel setting on the shoulders? A: The channel setting provides a sleek, modern look by enclosing the accent stones between two walls of metal. This protects the stones' girdles from impact and creates smooth, snag-free lines along the ring's shoulders.
