Starlit Tanzanite Oval Ring with Multi-Row Diamond

1. Measure Your Finger

For this method, you’ll only need a pen, a strip of paper, and a ruler. Cut out a narrow paper strip about 10 cm long and wrap it lengthwise around the finger you plan to wear the ring on. Mark the overlapping end with a pen and measure the marked length with the ruler. The result in millimeters corresponds to your ring size. For example, a measurement of 54 mm corresponds to ring size 54.

2. Use an Existing Ring

Another simple way to ensure you get the right size is to use an existing ring and measure the inner diameter or circumference. Multiply the value by 3.14, and the result corresponds to the ring size. You can also check out our handy international size converter if you know your size in another region. Practical Tip: If your existing ring falls between two sizes, we recommend choosing the larger one.

Do you need help selecting the right ring size?

We’ve created a measuring tape to make it as easy and quick as possible for you to find your ring size. You can find it here: Download Measuring Tape. Simply print it out, cut along the lines, and measure the size of the finger you plan to wear the ring on. Please note that size may vary throughout the day, as fingers can be slightly wider in the evening than in the morning. Therefore, it’s a good idea to measure twice before placing your order.
