How to choose the correct ring size

A perfect ring should be snug enough not to fall off, but loose enough to pass over the knuckle with minimal resistance.

Method 1: Measure a ring you already wear

If you already own a ring that fits your desired finger perfectly, this is the simplest method.

Choose a ring that fits well on the finger where you intend to wear the new jewelry.
Use a ruler to measure the internal diameter of the ring (in millimeters).
Measure exactly the empty space in the middle of the ring, without including the thickness of the metal.
Consult the table below to find the corresponding size.

Method 2: Measure your finger circumference

If you don't have a ring handy, you can measure your finger directly.

Wrap a piece of string, a strip of paper, or a tailor's tape measure around the base of your finger.
Mark with a pen the point where the ends overlap.
Measure the length of the string/paper with a ruler (in millimeters). This is the circumference.
Check the size chart below.

Useful tip: If you are between two sizes, we recommend choosing the larger one.

Important tips for accurate measurement

Time of day: Fingers can vary in size throughout the day. It is best to measure in the evening when fingers tend to be slightly more swollen.
Temperature: Cold can make fingers appear thinner, while heat expands them. Measure at room temperature.
Ring width: Very wide rings (over 5-6 mm) tend to feel tighter. In this case, it is advisable to choose a half size larger.
Hand matters: The dominant hand (the one you write with) is usually more developed. Measure the exact finger on which you will wear the ring.
