A guide to ring sizing and jewelry lengths, for both our international and Sri Lanka stores.
If you already have a ring that fits the intended finger well, the most reliable way to size it is to take it to any local jeweler and ask them to measure the inner diameter — free almost everywhere, and more accurate than a printable chart.
Without one on hand: wrap a strip of paper or string snugly around the base of the finger, mark where it overlaps, measure that length in millimeters, and compare it to the circumference column below.
| US | UK | EU | Circumference (mm) |
|---|---|---|---|
| 4 | H | 47 | 46.8 |
| 5 | J½ | 49 | 49.3 |
| 6 | L½ | 52 | 51.9 |
| 7 | N½ | 54 | 54.4 |
| 8 | P½ | 57 | 56.9 |
| 9 | R½ | 59 | 59.5 |
| 10 | T½ | 62 | 62.1 |
| 11 | V½ | 64 | 64.6 |
| 12 | X½ | 67 | 67.2 |
A piece listed with a specific ring size is made to that size only — check the product page's own Ring Size spec before ordering. Get in touch through the item's message thread if you need a different size and resizing is possible for that piece.
Where a length typically falls varies by neckline and build — use this as a starting point, not a rule.
| Style | Length | Typically Falls At |
|---|---|---|
| Choker | 14–16" | Base of the neck |
| Princess | 17–19" | Collarbone |
| Matinee | 20–24" | Top of the bust |
| Opera | 28–36" | Below the bust |
| Rope | 36"+ | Waist or lower |
Wrap a soft measuring tape (or a string, then measure the string) around the wrist just below the wrist bone. Add ½" (about 13 mm) for a comfortable fit, or ¼" (about 6 mm) for a snugger one, then compare to the bracelet's own listed length on its product page.
