Bergeon 1311-A Metal Ring Finger Gauge-Euro Size Flat Band

The Bergeon 1311-A Metal Ring Finger Gauge is a precision European-standard sizing tool built for professional jewelers and bench workers who require more measurement detail than the standard USA sizing system provides. Constructed from nickel with a flat band profile, this seamless gauge set delivers both diameter and circumference readings in metric units alongside the European standard size scale — making it an essential reference tool for working with international clientele or continental sizing standards.

Made in France, this is the only metal ring gauge set of this type manufactured outside of India, offering a level of durability and craftsmanship built to withstand many years of professional use.
