Oura just dropped a collection of announcements that fundamentally change how we think about smart rings. The big story? The Finnish health tech company is introducing the Oura Ring 4 Ceramic—its first non-metallic smart ring collection featuring four vibrant colors. But that's just the beginning.

The Oura Ring 4 Ceramic Collection: When Tech Meets Jewelry

The new rings are crafted from high-performance zirconia ceramic, a material traditionally found in fine jewelry and medical applications like dental crowns. This isn't your typical tech wearable anymore—it's genuinely beautiful hardware.

Four Color Options:

  • Tide (light aqua/green)
  • Petal (soft pink)
  • Cloud (off-white)
  • Midnight (dark blue)

Here's what makes the material special: Unlike painted or coated finishes, the color comes from natural minerals in the ceramic itself, meaning it stays vibrant and won't fade over time. Each ring undergoes a traditional firing process that strengthens the material and delivers a smooth, polished finish, with a hardness rating of 8.5 on the Mohs scale—harder than steel.

The Trade-offs:

  • Priced at $499 (compared to $349 for the titanium Ring 4)
  • Slightly thicker at 3.5mm versus 2.9mm for the standard version
  • Heavier, weighing between 5.1 and 8.1 grams depending on size
  • Can develop scuffs from softer metals like dumbbells, but these marks are reversible and can be wiped off with the included Ceramic Polishing Pad

Finally: The Oura Charging Case

After four generations, Oura is addressing one of users' most frequent requests. The new $99 charging case stores up to five full ring charges, fits easily into a pocket or bag, and uses USB-C for universal compatibility.

The clamshell design can complete one ring charge and fully charge the case itself in 90 minutes. Made from recycled aluminum with an anodized finish and a silicone insert inside, the case is dust and splash-resistant. One caveat: each case is size-specific to your ring.

Unlike competitors like Samsung's Galaxy Ring that bundle charging cases, Oura is selling this as a separate accessory. It's launching "in the coming months," so not immediately available despite being announced today.

Multi-Ring Support: Match Your Ring to Your Mood

Here's where things get interesting for the fashion-conscious. Oura is introducing the ability to pair and switch between multiple Oura Ring 4 devices under a single account. Whether you're switching rings for a workout, matching an outfit, or using a backup while charging, the transition is seamless.

Availability:

  • iOS: October 1, 2025 (today)
  • Android: Starting October 20, 2025

This feature transforms the Ring 4 from a single wearable into a collection you can curate. It's a bold move that positions Oura less as a pure health tech company and more as a lifestyle brand.

Health Panels: Lab Testing Meets Your Oura App

Oura announced Health Panels, a $99 service that allows US-based members to schedule cardiometabolic blood tests at one of 2,000 Quest Diagnostics labs directly through the Oura app. The service analyzes over 50 different biomarkers and links results to the ring's continuous data on sleep, readiness, and activity.

Results are clinician-reviewed and delivered within the app, where the new Oura Advisor feature allows users to ask AI-powered questions about their results and receive personalized tips. It's HSA- and FSA-eligible and will be available in the coming weeks to members ages 18-64 in most US states (excluding Arizona, Hawaii, New Jersey, New York, and Rhode Island due to state regulations).

This puts Oura in direct competition with services from Whoop and Ultrahuman, who offer similar lab testing integrations.

Ring Recycling Program

Oura is launching device recycling, giving members a convenient way to return their old rings as they upgrade to new generations, switch styles, or receive replacements. It's not a traditional trade-in program with discounts, but rather a responsible disposal option for size-specific hardware.

The Bottom Line

Oura is flexing its market-leader position with these announcements. The company revealed it has sold over 5.5 million rings since 2015, with more than half of those sales coming in the last year alone. Revenue exceeded $500 million in 2024—more than double the prior year—and they're projecting to reach $1 billion in 2025.

The ceramic collection is available now, the charging case arrives later this year, and multi-ring support is rolling out starting today on iOS. These aren't just iterative updates—they represent Oura's evolution from health tracker to fashion-forward wellness companion.

Whether you're drawn to the vibrant Tide color or planning to build a collection to match your wardrobe, Oura is betting that the future of wearables is personal, expressive, and undeniably stylish.
