Oura is reimagining the smart ring as a piece of jewelry with the Oura Ring 4 Ceramic, a family that emphasizes color, shine, and fashion without changing the health tech inside. The new model, which has a zirconia ceramic edge and comes in Cloud (white), Tide (light blue), Petal (light pink), and Midnight (navy), is more like an accessory that you’d actually build an outfit around, with wellness-tracking functions.
A Ceramic Take On A Time-Tested Platform
Zirconia ceramic is a clever choice of material. This material, known from high-end watchmaking and even dental implantology, is durable, hypoallergenic (no nickel!), and keeps a shiny appearance. Oura’s iteration is decidedly sleek and, full disclosure, slightly thicker than the regular ol’ Oura Ring 4 — leaning toward statement over barely-there band.
It is hard enough that softer metals — think keys or gym machines — can leave superficial gray marks in its finish. Oura includes a ceramic polishing pad to buff out those scuffs, a pragmatic acknowledgment of life’s daily wear and tear on glossy surfaces.
The Same Health Engine Under the Ceramic Shine
Beneath the ceramic shell, its hardware and core metrics match those of the Oura Ring 4: optical heart-rate sensors, skin-temperature sensing, and motion tracking power Readiness, Sleep, and Activity scores. The company’s temperature measurements have been used by research institutions including the University of California, San Francisco, and the Rockefeller Neuroscience Institute, which does much to bolster Oura’s credibility when it comes to more than just lifestyle monitoring.
That is to say: you’re not sacrificing signal for style. And while it maintains the familiar proportions and multi-day battery life of its current platform, the ceramic version tracks the same nightly trends — sleep stages, heart rate variability, and overnight temperature shifts.
Multi-ring Support for Easy Rotation Between Rings
Oura is also introducing multi-ring support, allowing one account to hand off data collection cleanly between rings. That little software tweak counts: it subtly trains wearers to think of the Ceramic as a dashier partner to a more mundane band, equipping them with the option to change up without sacrificing continuity in longer-term trends.
For a category that thrives or dies by consistency, frictionless switching is savvy. The one-to-the-second readout and hardware can keep up with a workday, a workout, or a black-tie affair.
Battery Life and Charging for Travel and Daily Use
Expectations for battery life haven’t changed from the Oura Ring 4, including multi-day run times that make it practical for monitoring your overnight sleep. The included charging case now holds about five full recharges, making it even more airline-friendly for longer trips. The case costs $99 and will be sold separately.
The extended case, combined with the Ceramic’s durable finish, is one thing that makes the ring feel closer to “always-on” — no anxious top-offs, no babying of the exterior.
The Smart Ring Race: Where Fashion Meets Function
Style is fast emerging as a competitive axis for smart rings. Samsung’s Galaxy Ring has upped category awareness, while the Ultrahuman, RingConn, and Movano’s Evie are focusing on niches like comfort, battery life, and women’s health. Movano has even received FDA clearance for pulse oximetry and heart rate measurements in Evie, marking a less crowded frontier where clinical rigor meets design.
As mainstream brands entered the category, analysts at Counterpoint Research said consumers are becoming more interested in such products. Oura’s answer, instead of pursuing eye-catching new sensors, is to refine the object — relying on its established metrics while rendering the ring both visible if you choose rather than simply discreet by default.
Cost, membership, and who the Oura Ring 4 Ceramic is for
The Oura Ring 4 Ceramic starts at $499, and you can purchase an optional membership for full insights into the data for $70 per year. Sizing, fit, and core metrics are identical to the standard Ring 4, so here, it’s aesthetic: you’re paying for material and finish that make a health tracker feel like jewelry.
For anyone who’s appreciated Oura’s data but needed a more aggressive look, the Ceramic is easily its most wearable form yet. “It’s a clear sign that the next wave of wellness tech isn’t just going to sit on a spec sheet, but it’s actually going to be out in the open, on your finger.”
