Oura Ring 4 Ceramic
Oura Ring 4 Ceramic takes everything that makes Oura Ring 4 exceptional and wraps it in a material that's in a class of its own.
The exterior is crafted from high-performance zirconia ceramic — fired through a traditional process that gives it superior scratch resistance, a polished luster, and vibrant colorways you won't find on titanium. Inside, the seamless titanium interior keeps the ring non-allergenic and skin-gentle, while the same Smart Sensing technology that powers all Oura Ring 4 models continuously adapts to your unique finger to capture highly accurate, continuous data.
The health tracking depth is identical: Sleep Score, sleep stages, SpO2, HRV, resting heart rate, skin temperature trends, Readiness Score, Daytime Stress, Illness Detection, 40+ auto-detected activities, and women's health features including Fertile Window. Four striking colorways — Midnight, Cloud, Petal, and Tide — make it easy to match your ring to your style.
If you own multiple Oura Ring 4 styles, you can now switch between them as easily as swapping jewelry. Requires Oura Membership. FSA/HSA eligible.

"It is very smooth, comfortable, and I like wearing it. I feel that it gives me good insight into my sleep patterns. Battery life seems great so far. It seems pretty accurate for me in terms of step count too, and is the only device I've found that actually recognizes when I'm playing a musical instrument, which absolutely should count as a workout!" — Verified Buyer, Best Buy
