# Trillion Ring with Crossed Prongs Welcome to RhinoArtisan! In this tutorial, we’ll walk through a complete, production-focused workflow for creating an elegant **classic shank ring with a trillion-cut center stone and crossed prongs**. Starting from a precise shank curve, you’ll learn how to position and orient the main gem, design custom SubD crossed prongs, and integrate side stones seamlessly into a clean, traditional shank. Throughout the process, we’ll combine curve-based construction, SubD modeling, and surface workflows to ensure the ring remains structurally sound, visually balanced, and fully manufacturing-ready. The tutorial continues with gemstone placement along the shank, detailed cutter configuration, pavé refinement on the prongs, and finishes with a secure basket for the center stone and final boolean operations — resulting in a polished model ready for rendering or production. 📌 **What You’ll Learn:**\ ✔ Creating a precise classic shank curve by size and region\ ✔ Positioning and orienting a trillion-cut center stone using Gem Studio\ ✔ Designing crossed SubD prongs using Blend curves and Pipes\ ✔ Advanced SubD editing: edge loops, bridges, symmetry, and smoothing\ ✔ Building and refining a clean classic shank using Sweep 1 Rail\ ✔ Using History to dynamically adjust and customize the shank profile\ ✔ Placing side stones along the shank with Gems on Curve\ ✔ Configuring micro cutters, V-cutters, and rails for secure stone settings\ ✔ Adding pavé stones on prongs and refining gem heights manually\ ✔ Creating and editing a custom basket for the center stone\ ✔ Final boolean operations for a clean, production-ready model 📢 **Why Watch This?**\ ✅ Learn a complete classic shank ring workflow from start to finish\ ✅ Master crossed prong construction for elegant and secure center stones\ ✅ Combine SubD flexibility with precise curve and surface control\ ✅ Build optimized geometry ready for 3D printing and casting\ ✅ Improve efficiency using RhinoArtisan’s specialized jewelry tools {% embed url="" %}
