Oura unveils Ceramic Ring 4 with multiring support and Health Panels

Oura introduced a ceramic version of its Ring 4 lineup on Wednesday, rolling out new hardware and services that expand the company’s design options and health-tracking capabilities. The launch includes the Oura Ring 4 Ceramic, a pocketable charging case, multiring software support and a paid blood-testing service that will be offered through the Oura app in the United States.

The Ceramic Collection replaces the ring’s metal finish with zirconia ceramic, a hard, jewelry-grade material Oura says is hypoallergenic and colored through minerals so the hue is integral to the material rather than a surface coating. The rings are offered in four shades — Midnight, Petal, Tide and Cloud — and come in sizes four through 15 for a flat price of $499. Oura will include a polishing pad with the ceramic model to address surface marks. The company said the ring preserves the same sensor and tracking technology as the titanium Ring 4, while the ceramic version is slightly thicker and heavier, measuring roughly 3.51 millimeters in thickness and weighing between about 5.1 and 8.1 grams depending on size versus the titanium model’s 2.88 millimeters and roughly 3.3 to 5.2 grams.
