Guldviva ring sizes are the inside diameter in millimetres (mm). A size such as 17.5 mm describes the space across the inside of the ring, not the circumference of your finger. Adjustable rings show a diameter range.
Measure a ring that fits
- Choose a ring that fits the finger on which you will wear your new ring.
- Measure straight across the inside, through the centre. Do not include the thickness of the metal.
- Compare that inside diameter with the sizes offered on the product page.
For a wide ring, or if you are between sizes, contact us for help choosing the fit. Rings can be difficult to buy online, which is why we offer one complimentary resizing within one month of purchase.

Necklace and bracelet lengths
Lengths are shown in centimetres, with approximate inches where provided. For example, 42 cm is approximately 16.5 inches, 45 cm is 17.7 inches and 50 cm is 19.7 inches. To compare necklace lengths, measure a necklace you already enjoy wearing; the position on the body varies with your proportions and the pendant.
