## Is 1.2 mm too thin for engagement ring?

Don’t go too thin

An engagement ring with a band (or shank) of at least 1.6mm-2.0mm provides a stable foundation for a center stone. Shanks thinner than 1.6mm may not hold up in the long-run. That’s why we recommend going no smaller than a 1.5mm band. If the band is too thin, it’s likely to crack or bend over time.
