Size Guide
Not sure which size to pick? Here's how to find your perfect fit for rings, bracelets, and necklaces.
Ring Size Guide
How to measure
Option 1 — Use an existing ring: Take a ring that already fits the intended finger well. Measure its inner diameter in millimeters, then match it to the chart below.
Option 2 — String or paper strip method: Wrap a strip of string or paper around the base of your finger, mark where it overlaps, then measure the length in millimeters. Divide by 3.14 to get the diameter, then match it to the chart below.
Tip: Fingers are slightly larger in the evening and in warm weather — measure a few times at different points in the day for the most accurate result.

Between two sizes, or measuring for a wide band? We recommend sizing up for a more comfortable fit.
Bracelet Length Guide
How to measure
Wrap a soft measuring tape (or a strip of string, then measure the string) snugly around your wrist, just below the wrist bone. For a looser, more relaxed fit, add 1–1.5 cm (0.5 in) to your measurement.
Standard Bracelet Sizes
| Size | Wrist circumference | Bracelet length |
|---|---|---|
| XS | 13–14 cm (5.1–5.5 in) | 15 cm (6 in) |
| S | 14–15 cm (5.5–5.9 in) | 16 cm (6.3 in) |
| M | 15–16 cm (5.9–6.3 in) | 17 cm (6.7 in) |
| L | 16–17 cm (6.3–6.7 in) | 18 cm (7.1 in) |
| XL | 17–19 cm (6.7–7.5 in) | 19–20 cm (7.5–7.9 in) |
Necklace Length Guide
Necklace length determines where the piece sits — here's a general guide (actual fit varies with neck size and pendant style):
| Length | Style | Where it sits |
|---|---|---|
| 35–40 cm (14 in) | Choker | Tight around the base of the neck |
| 40–45 cm (16 in) | Collar | Sits at the collarbone |
| 45 cm (18 in) | Princess | Just below the collarbone — most popular everyday length |
| 50–55 cm (20–22 in) | Matinee | At or just above the bust |
| 60–70 cm (24–28 in) | Opera | Below the bust |
| 90 cm+ (36 in+) | Rope | Long, often worn doubled |
