Oura has just launched the Ring 4 Ceramic ( 2025 ), featuring four new colors, zirconia ceramic construction, and the same technology that health enthusiasts rely on. Now, it’s stylish enough to be considered jewelry.
The price in the US starts at $499.00. , and it’s now up for pre-order on Amazon US.
The Colors You’ll Actually Want
Forget black and silver. Oura’s going full nature palette:
Cloud – Off-white with grey undertones. The “goes with everything” option inspired by traditional kaolin ceramics.
Tide – Pastel blue-green that channels celadon glazes. Looks good on literally every skin tone.
Petal – Blush pink with lilac hints. Subtle enough for meetings, fun enough for weekends.
Midnight – Deep cobalt blue. For people who want their health tracker to look moody and expensive.

Why Ceramic Matters
Zirconia ceramic isn’t just pretty. It’s tough – 8.5 on the Mohs hardness scale, harder than steel, almost as durable as sapphire. It’s also biocompatible (same stuff used in dental crowns and joint implants), hypoallergenic, and lightweight enough you’ll forget you’re wearing it.
The catch? Ceramic can scuff when it rubs against softer metals. Your dumbbells and cookware might leave marks. It’s jewelry-grade material, so treat it like jewelry.
