Read a ring’s approximate size on a marked mandrel or support suitable practice work at a jewelry bench.

Features and specifications

Who it suits

Useful for organizing rings by size and for trained hobbyists working with compatible plain bands. Let a ring rest naturally rather than pushing it farther down the taper.

Before you choose

A mandrel reading is not a guarantee of comfort or fit on a finger. Wide, shaped, stone-set, or fragile rings need extra care. Do not hammer or stretch valuable jewelry without appropriate training.

Check the selected model, seller, included accessories, and current price on Amazon before ordering.
