What is the strongest necklace chain type?

The strongest chains for daily wear are cable, curb, and figaro in 1mm or thicker. Avoid snake chains (they kink and are impossible to repair) and very thin rope chains under 0.8mm. Sterling silver or 14k gold-filled lasts years.

Remove tennis bracelets before showering. Soap gets in the stones and dulls them, and wet skin makes the bracelet slide and risk catching. The clasp on a tennis bracelet is the weak point. Take it off to sleep too.
