The Ring Layout Mandrel was designed by professional jeweler/engraver, Todd Daniels, to help artists more efficiently lay out rings. The mandrels 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.
