Ring size guide

Not sure of your ring size?

1. Measure a ring that already fits

Measure the inside diameter at the widest point in millimetres. An inside diameter of 17.0 mm corresponds to ring size 17.0.

2. Measure your finger

Use a narrow strip of paper, keep it snug but not tight, and measure the circumference in millimetres. Measure 2–3 times, preferably later in the day.

Between two sizes? Ring width and your knuckle also affect fit. Ask us before ordering if you are unsure.
What if the size is not quite right?

For a ring purchased from us, you get the first ring size adjustment at a reduced price compared with our standard price, if the ring can be resized.

Finger size naturally varies.

Your finger can be a different size in the morning and evening, as well as in warm and cold weather. A ring does not need to feel exactly the same every day. A size adjustment is worth considering only if the ring is repeatedly too tight or too loose at different times.

14K or 18K gold?

14K gold contains 58.5% pure gold. The alloy is typically harder and usually more affordable.

18K gold contains 75% pure gold. It has a higher gold content and, for the same ring model, costs more than the 14K version.

Both are genuine gold and suitable for everyday rings.

Natural or lab-grown diamond?

Natural diamond formed in nature over a very long period of time.

Lab-grown diamond is a real diamond grown in controlled laboratory conditions. Its crystal structure and essential material properties are the same; the key difference is origin.

At the same size, a lab-grown diamond is less expensive than a natural diamond.
