Many different metal types are used to make jewelry.

We've listed some popular metals and their Mohs level below.

The Mohs scale is a system used to rank materials on their hardness, which is graded using numbers from 1 to 10.

The Mohs scale is used to compare gemstones, metals, and other materials to evaluate their durability. This can indicate whether other metals can scratch each other.
