The Ring Layout Mandrel was designed by professional jeweler/engraver Todd Daniels to help artists lay out rings more efficiently. The mandrel’s circumference is measured into 10° intervals with markings at 0°, both 90°, and 180°. This helps accurately split a ring into quadrants for more precise spacing when laying out stones, scrolls, design elements, and more.
Tapered shape for use with a wide variety of ring sizes, from approximately 1.5 to 12.5 (12.8 – 21.9 mm)
