Best Gemstones for Rings: Durability Beyond Mohs Hardness

Rokero Gems Editorial · Updated 4 October 2026

Choose ring gemstones using hardness, toughness, cleavage, treatments, setting protection and daily wear.

Toughness, cleavage, inclusions, treatments, exposed corners and setting design also affect risk.

Match the gem and setting to the wearer's daily activities and willingness to remove the ring when needed.
