A 1‑piece stepped stainless steel ring core in 6 mm width and size 12.5—crafted for makers who want clean transitions, secure material seating, and a professional finish on custom wood, resin, hybrid, or crushed‑stone rings.

The Step 6 mm – Size 12.5 Ring Core features an integrated step that helps guide your shaping and ensures your inlay material meets the metal shoulder neatly. This creates a crisp, defined edge and improves alignment during turning, sanding, and polishing. The single‑piece design offers simplicity and strength, making it ideal for both beginner and experienced ring makers.

Made from high‑quality stainless steel, this core is hypoallergenic, corrosion‑resistant, and built for everyday wear. The 6 mm width provides a comfortable, modern profile suitable for minimalist bands or detailed inlay designs.
