For years, health wearables have been designed to blend into your life without drawing attention. Today, that changes. Say hello to Oura Ring 4 Ceramic, a colorful new expression of the world’s leading smart ring that pairs refined style with everyday durability.
With four stunning new colors to choose from—Cloud, Tide, Petal, and Midnight—Oura Ring 4 Ceramic empowers you to express your personal style while gaining a deeper understanding of your overall health and wellbeing.
This colorful new evolution is built with the same cutting-edge technology of Oura Ring 4, including Smart Sensing technology, which adapts to your finger to deliver accurate, continuous data. And with five to eight days of battery life, you’ll see a complete picture of your health—without interruptions.
Crafted from high-performance zirconia ceramic, a material prized in fine jewelry for its exceptional durability, lightweight comfort, and skin-friendly nature, the new Ceramic Collection is more than a refresh; it marks a bold step forward for Oura.
Encased in High-Performance Ceramic
When determining the best material for our Ceramic Collection, zirconia ceramic stood out as the clear choice. This premium material is not only incredibly lightweight, but it’s also surprisingly durable. In fact, with a Mohs hardness scale rating of 8.5 out of 10, it’s harder than steel and approaching the durability of sapphire.
Ideal for daily wear, zirconia ceramic is a biocompatible and non-allergenic material, commonly used in medical applications like dental crowns and joint implants. Like Oura Ring 4, the Ceramic Collection features recessed sensors on the interior, making it incredibly comfortable and gentle, even on sensitive skin.
Each Oura Ring 4 Ceramic undergoes a traditional firing process that strengthens the material and gives it a smooth, polished finish. Plus, the use of premium, body-friendly materials like ceramic draws on our decade-long history: The very first Oura Ring was also made from ceramic. This brand-new iteration brings the material life in a fresh and innovative way with groundbreaking technology, high-end material, and expressive colors.
Oura Ring 4 Ceramic is a finely crafted piece of jewelry that, like most premium goods, requires a little maintenance to look its best. Due to zirconia ceramic’s hardness, it can scuff—which means it can take on the color of softer metals, like a dumbbell or cookware. Learn how to keep the ceramic looking its best here.
Inspired by the Beauty of the Natural World
Oura Ring 4 Ceramic is available in four unique colors inspired by nature: Cloud, Tide, Petal, and Midnight. Each color was carefully chosen to complement every skin tone and accent your style and personality, making your technology as unique as you are.
Cloud offers a soft, off-white finish with a hint of grey—the perfect neutral tone for whatever you’re wearing. Cloud is inspired by the traditional kaolin color of traditional ceramics. Shop Cloud here.
Tide captures the serene blue of the ocean in a light, pastel blue-green hue. Inspired by traditional celadon glazes used in Asian ceramics, the fresh and unique finish complements any skin tone. Shop Tide here.
Petal is a light, blush pink with lilac hues inspired by common ceramic glaze practices. It’s subtle enough for everyday, with a fun and floral pop of pink. Shop Petal here.
Midnight offers a dark, captivating blue, reminiscent of a clear night sky. Deep and dynamic, Midnight is tinted with a cobalt pigment used in traditional ceramics. Shop Midnight here.
Powered by Cutting-Edge Technology
While the exterior of Oura Ring 4 Ceramic is new, the technology inside contains the same groundbreaking innovation that Oura is known for.
Like Oura Ring 4, the Ceramic Collection is powered by Smart Sensing technology, which adapts to your finger to deliver accurate, continuous data.
