What is the Oura Ring made from?

The Oura Ring 4 has arrived, with new features packed into a fresh design. The latest smart ring has a simplistic, round design that makes it look like any regular ring. However, the dome sensors have been recessed to improve the accuracy of your health readings, which have become even more accurate thanks to a new platform called Smart Sensing that gathers information from 18 pathways. It’s sure to end up on our list of the best smart rings when it comes out.

But what is the Oura Ring made from? Is it a precious metal like gold, or perhaps silver? You might be wondering what the Oura Ring 4 is made out of. Lucky for you, we crafted this nifty little guide to tell you exactly what material it’s crafted with and the benefits of that material. Read on to find out.

Despite the appearance of its many finishes, the Oura Ring 4 is made out of titanium. Titanium is lighter than gold, but it’s strong. In fact, it’s the strongest metal in the periodic table of elements because it has the highest strength-to-weight ratio, with a density of 4.5 grams per cubic centimeter and a Mohs hardness of 6.0. Conversely, gold has a density of 19.3 grams per cubic centimeter and a hardness rating of 2.5 on the Mohs scale of mineral hardness. Because of its lightness, titanium is the most comfortable material to wear on your finger. However, that lightness does mean it tends to lack the premium “heft” of gold and other precious metals, so it can feel cheap. Be assured that it absolutely is not.

Aside from the Oura Ring, titanium is used in various forms of jewelry, from earrings to bracelets, because it’s a biocompatible material, meaning it’s largely inert and doesn’t adversely react with your body. It’s also hypoallergenic, making it less likely to cause skin irritations, which is very important for people with certain skin conditions.

Titanium is highly durable and resistant to bending and scratching, but it can still take some scratches. It also tends to scratch other jewelry made of softer metals, like sterling silver. If you wear the Oura Ring, you may want to be careful not to let it scratch against any necklaces, bracelets, or watches made of those metals. Don’t wear other rings next to the Oura Ring because they’ll get scratched by it if they rub against it.

The Oura Ring 4 is available in black, silver, Stealth, brushed silver, gold and rose gold. The black and Stealth rings have a physical vapor deposition (PVD) coating on the outer shell, while the other colors have a diamond-like carbon (DLC) coating.

The black ring has a glossy tungsten PVD coating, making it more durable. The Brushed Silver ring was created using  a technique called vertical brushing that allows it to reflect light at every angle and accentuate the properties of titanium. Thanks to its matte black finish, the Stealth ring contains an additional layer of precision and detail. Silver and Gold just have a glossy finish, while the Rose Gold ring has a glossy finish designed to develop a darker patina over time, depending on how you take care of it and how often you wear it.
