Oura Ring Materials

All new Oura ring designs are wrought out of titanium and are water-resistant to 150 meters. The rings have a seamless, non-allergenic inner molding.  

The rings are coated for improved scratch resistance. Depending on the ring color, we use two similar types of coating methods: DLC and PVD coating.

  • Black and Stealth rings have a DLC coating
  • Silver rings have a PVD coating and a Chromium Nitride coating.

The rose rings have real rose gold PVD coating, and their scratch resistance is on par with common jewelry standards.
