Oslo Onyx Signet Ring

Sterling silver is a precious alloy with the number 925 indicating its purity. This means that 92.5% of the composition is pure silver, while the remaining 7.5% is usually copper or other metals to increase strength and durability.

Our sterling silver products are stamped with 925, which is a recognized symbol for this precious metal.

We know it can be difficult to know your ring size for different fingers. Remember, we offer free exchanges if the size doesn't fit, and you can easily contact us here if you have any questions.

You can use three different methods to find your perfect size. At Leo Chevon, we indicate ring sizes according to EU sizes. We offer the following sizes in most of our rings: 49, 52, 54, 57, 59, 62, 64, and 67.

METHOD 1

Now you can quickly and easily find your ring size with our free ring sizer. Search for “Ring Sizer” to find the tool.

METHOD 2 Tie a thread around the finger you want to measure. Don't tie it too tight. Then measure the length of the thread in mm. The length of the thread corresponds to your size. If you're between two sizes, choose the larger one. For example, if you get 58 mm, choose size 59.

METHOD 3 Use a ring that fits and measure its inner diameter in mm using a measuring tape. Then multiply the measurement by 3.14. If the calculation, for example, gives 61.8, you should choose size 62.

Good luck, and feel free to contact us here if you have any questions.
