Does titanium jewellery rust or degrade over time ?

Titanium jewellery is exceptionally resistant to rust and degradation. Unlike metals containing iron, which are prone to rust, titanium is entirely iron-free, meaning it cannot rust. When exposed to air, titanium develops a natural oxide layer that protects it from further oxidation and environmental damage. This layer is self-repairing, meaning it will reform if scratched, continually protecting the metal underneath. This unique characteristic of titanium makes it highly durable and capable of maintaining its appearance and structural integrity over many years, even in harsh environments like saltwater or extreme temperatures.
