The Oura Ring 4 Ceramic is a smart ring that combines cutting-edge health tracking with refined style in four stunning colorways.
Crafted from high-performance zirconia ceramic with a smooth, polished finish, this health tracker monitors over 50 wellness metrics including sleep quality, heart rate variability, stress levels, blood oxygen, body temperature, and women's health—all from your finger.
Smart Sensing technology adapts to your finger for highly accurate, continuous data collection without the bulk of a smartwatch. With 5-8 days of battery life, water resistance up to 100 meters, and seamless integration with the Oura app's AI-powered insights, it delivers personalized daily readiness scores, activity goals, and stress recovery guidance.
Available in Midnight, Cloud, Tide, and Petal, the ceramic finish offers superior scratch resistance compared to titanium while looking like jewelry rather than tech.
