Smart ring design is a bit of a snooze in 2025. Even the best smart rings all look pretty much the same: a standard circular band in your choice of several metal finishes. Not a fan of metal jewelry? Prior to today, you’d be out of luck. Fortunately, Oura’s new ceramic smart ring collection is here to save the day.
The new Oura Ring 4 Ceramic is exactly what it sounds like: the guts of an Oura Ring 4, with a fancy, new ceramic exterior. With four colors to choose from, including an eye-catching aqua/light-blue option, I'm admittedly more than a little hyped on these (and eager to get one on my finger!).
Oura Ring 4 Ceramic

This is Oura’s first non-metal smart ring, and it sure is a beaut! It comes in four colors, including Midnight (dark blue), Pedal (light pink), Tide (light aqua), and Cloud (off-white).
While the standard Oura Ring 4 starts at $349, the Ceramic models are $499.
The zirconia ceramic exterior is particularly hard and scratch-resistant. Oura also notes that the color is inherent to the material and not a finish/coating. This means that your new Oura Ring 4 Ceramic should maintain its stunning color for the life of the device.
Like the Oura Ring 4, the Oura Ring 4 Ceramic will be available in sizes 4 through 15. While the onboard tech is the same, the Ceramic models are notably heavier than the metal options.
The standard Oura Ring 4 weighs between 3.3 grams and 5.2 grams, depending on size, but the Ceramic edition is between 5.1 grams and 8.1 grams. The Ceramic is also a little thicker, 3.5mm versus 2.9mm.
Oura Ring Charging Case

Once fully juiced up, the new Oura Ring Case can recharge your Oura Ring 4 or Oura Ring 4 Ceramic up to five full times. Charge time takes roughly 90 minutes. Unfortunately, the new $99 Oura Ring charge case doesn’t seem to support older models like the Oura Ring Gen 3.
The new case is also size-specific, which seems a bit odd/unfortunate. This means that if both my partner and I are Oura Ring 4 owners, we can’t share a case when traveling.
Splash and dust-resistant, the new Oura Ring Case is a clamshell-style, and features an anodized aluminum exterior with a soft silicone interior.
Oura multi-ring support

If you already own an Oura Ring 4 (or prior model) and are tempted by one of the new Ceramic models, Oura has gone about making switching between models a painless affair. With multi-ring support, Oura owners can select their ring of choice from within the app with just a few taps and switch rings or add a new ring with similar ease.
In addition to the above, Oura also announced a new recycling program that’ll make it easier and more sustainable than ever to trade in a busted or outdated Oura Ring.
