size guide
All Mantor rings are measured in EU sizing (inner circumference in millimeters).
Note:
Due to the solid, wide-profile design of our rings, they fit snugger than standard thin bands. If you are between two sizes, we recommend selecting one size up.

How to Measure
Option 1: Measure an existing ring
Place a ring that fits you well flat on a ruler and measure the inside diameter in millimeters (excluding the metal).
Option 2: Measure your finger
Wrap a strip of paper around the base of your finger or knuckle, mark where it overlaps, and measure the length in millimeters against a ruler. That measurement corresponds to your EU size.
Fit Tips
- If your knuckle is wider than the base of your finger, pick a size between both measurements so the ring slides over smoothly.
- Measure at room temperature in the late afternoon, as fingers can be slightly slimmer in the morning or cold weather.
Mantor TOR ONE is a model of our TOR series for focused & self-controlled men – with an eye-catching diamond set into a strip of gold.
Solid .925 sterling silver, rhodium-coated, with a brushed top plate and high-polish sides.
A vertical gold inlay cuts through the front like a spine, ending in a square-set diamond, thus creating a clear and impressive design.
The rings of our TOR series are produced in two different locations by manufacturers whose production meets Mantor’s highest quality standards.
The design of both model ONE & model TWO of Mantor's TOR series has been registered under EUIPO No. 015148522-0001 since 21/07/2026.
