Let’s be honest, most tech wearables are bulky and not exactly what you’d describe as pretty. But when you’re regularly wearing something on your hands, you probably want it to look nice and perhaps even blend in with the rest of your jewelry. That’s the idea behind Oura’s newest smart ring, the Oura Ring 4 Ceramic. The Ring 4 Ceramic is Oura’s first collection of smart rings that doesn’t feature metallic finishes. Instead, they’re made from zirconia ceramic, a more wear-resistant material that, Oura says, delivers both style and comfort. I’ve tested the Oura Ring 4 Ceramic for the past three weeks, and here’s what I’ve found. Before diving into the specifics, it’s worth noting that since the software behind the Oura Ring 4 Ceramic is the same as the Oura Ring 4, I won’t be delving too deeply into the software and hardware side of things. For that, you can check out our Oura Ring 4 review. Finish and feel The Oura Ring 4 Ceramic comes in four colors: Midnight (dark blue), Cloud (white), Tide (light teal), and Petal (light pink). The ring costs <head>50 more than the starting price of the standard Ring 4, with a $500 price tag, and is available in sizes 4-15. I opted for Midnight. Although the shade is technically dark blue, it can appear black from afar — or even a dark shade of green, I’ve been told. The ring doesn’t look like a tech wearable at first glance, which is nice if you want to prioritize aesthetics without sacrificing functionality.

The titanium version is 2.88 mm thick, while the ceramic version measures 3.51 mm. Techcrunch event San Francisco | October 13-15, 2026 As for the weight, the ring can weigh between 5.1 and 8.1 grams, depending on the size you get, making it heavier than the Titanium Ring 4, which weighs between 3.3 and 5.2 grams. Despite the Oura Ring 4 Ceramic being thicker and heavier than its predecessor, I found it to be comfortable and lightweight, even when compared to a standard metal band. It feels like a regular ring, just marginally thicker. The ring is smooth and not as prone to collecting fingerprints as the titanium versions of the Ring 4. Since the zirconia ceramic is warmer and less slick than the titanium rings, the Ring 4 Ceramic can feel a somewhat “sticky” at times, meaning the outside of the ring might cling to the sides of your fingers, but I adjusted to the feel of the ring pretty quickly. Oura says the color on the rings comes from natural minerals in the ceramic itself, so it stays vibrant and doesn’t fade over time. (Of course, I’ve only had the ring for three weeks, so I can’t speak to its long-term durability, but so far, the color is identical to what it was on day one.) Durability Oura says the Ring 4 Ceramic is prone to scuffs from softer metals, like those found in cookware or dumbbells. The company says these scuffs can be addressed with the Polishing Pad that comes with the ring. (The review unit I received from Oura did not include the Polishing Pad, however.) The company also recommends wearing the ring on your non-dominant hand to avoid unnecessary impact. However, the ring just felt right on my dominant index finger, so that’s where I wore it for the past three weeks. This exposed it to more potential damage in a briefer period of time than a typical customer might experience.

I wasn’t sure how well the ring would hold up with me hauling my luggage around, accidentally hitting the ring on a few counters (I’m clumsy!), or letting it brush against the airplane window when I leaned in for a nap. As it turned out, the ring made it through all of that unscathed. There were even a handful of moments when I was certain I had scratched it — like when I was holding on to a rusty railing walking up the steps of the Point Arena Lighthouse, forgetting that I had the ring on, or when I forgot to remove it before doing the dishes. But the ring didn’t end up with any marks or permanent damage. It’s worth mentioning that although the ring is water-resistant up to 100 meters, which means you can wear it while doing the dishes or showering, I took it off while doing the dishes because Oura warns that the ring can scuff when it comes into contact with softer metals. Since I’ve had less than a month with the ring,
