Bergeon 5236-C Swiss-Made Hi Precision Ring Finger Gauge

The Bergeon 5236-C is a professional-grade ring finger gauge set engineered for precision sizing across an exceptionally broad range. Constructed from high-impact durable plastic with color-coded rings for quick visual reference, this Swiss-made tool delivers reliable results at the bench. Each gauge displays dual measurement systems on opposite sides, making it equally useful for working with clients and for technical ring sizing tasks.

One side is marked with USA sizes 1 through 15 alongside diameter measurements in millimeters (13–24.2 mm). The reverse side displays French sizes 1 through 36 alongside circumference measurements in millimeters (41–76 mm). This dual-sided format eliminates guesswork when communicating across different sizing standards.

What sets this set apart is its expanded range: 36 individual ring sizes instead of the typical 30. The seven additional sizes — 3, 5, 7, 8, 10, 12, and 13 — fill in gaps commonly missing from standard sets, ensuring accurate sizing for a wider range of customers and ring styles.
