Jewellery Size Guide
Finding the right fit makes jewellery more comfortable to wear and helps each piece sit as intended.
Please note: Jewellery made to order in a custom size is non-returnable, so it is important to get your size right before ordering. If you are at all unsure, please contact us and we will be happy to help you choose the correct size.

How to measure your ring size
- Wrap a flexible tape measure or a thin strip of paper around the base of your finger. Mark where the ends meet and measure the length in millimetres — this is your circumference.
- Alternatively, measure across the inside of a ring that fits well at its widest point to find the inside diameter.
Measure when your hands are at a comfortable room temperature. Fingers can be slightly smaller when cold and larger in warm weather. If you fall between two sizes, choose the larger one — it is easier to resize a ring down than up.
Ring sizes can also vary slightly depending on the shape and width of the band. Wide bands tend to fit more snugly, so you may need to go half a size up. Please contact us when choosing between two sizes and we will be happy to advise.
Bracelet & Bangle Size Guide
| Size | Wrist circumference (cm) | Wrist circumference (inches) |
|---|---|---|
| Extra Small | 12.1–13.3 | 4.76–5.25 |
| Small | 13.4–14.6 | 5.26–5.75 |
| Medium | 14.6–15.9 | 5.76–6.25 |
| Large | 15.9–17.1 | 6.26–6.75 |
| Extra Large | 17.2–18.4 | 6.76–7.25 |
| XXL | 18.4–19.7 | 7.26–7.75 |
| XXXL | 19.7–21.0 | 7.76–8.25 |
Choosing your fit
- Close fit — measure your wrist and add minimal room. Suits cuffs and solid bangles.
- Comfortable fit — add 1–1.5 cm to your wrist measurement. A good all-round choice.
- Relaxed fit — add 1.5–2 cm. Suits chain and link bracelets that need room to move.
Cuffs and solid bangles sit closer to the wrist, while chain and link bracelets normally need additional room for movement. If you are unsure, opt for comfortable fit.
Necklace & Pendant Length Guide
| Length (inches) | Length (cm) | Typical position |
|---|---|---|
| 16" | 40.5 cm | Close to the base of the neck |
| 18" | 45.7 cm | Around the collarbone |
| 20" | 50.8 cm | Just below the collarbone |
| 24" | 61 cm | Upper chest |
| 30" | 76.2 cm | Mid-chest |
| 36" | 91.5 cm | Long necklace length |
Necklace length affects where pieces rest on the body and varies by neck size, body shape, pendant dimensions, and clothing neckline. To test a length before purchasing, cut a piece of string to the desired measurement and hold it around your neck.
Note that pendants alter where a necklace appears to sit — a larger or heavier pendant will draw the chain lower than the chain length alone suggests.
