Shown to scale on a finger. Drag to try weights, or pick one in the size guide to select it on the product.
Approximate face-up size by carat weight for a round diamond, shown close to actual size on screen. Tap a row to choose that weight.
Measurements are approximate and vary slightly with cut proportions. Carat is a measure of weight, not size.
Ring size guide
Lay a ring you own flat on the circle and slide until it sits just inside it — or set its inner diameter directly.
Hold a bank card to the screen and match the outline
Cards are 85.6 mm wide worldwide — this makes the circle physically true to size, and we remember it next time.
Between sizes? Always choose the larger size. Fingers are slightly bigger in the evening — measure then for the best fit.
Method 1 — Use an existing ring
- Find a ring that fits the intended finger comfortably.
- Place it flat and measure the inner diameter (inside edge to inside edge) in mm.
- Enter that measurement in the Measure a ring tab.
Method 2 — Wrap and measure
- Wrap a thin strip of paper around the base of your finger.
- Mark where it overlaps — measure that length in mm (your circumference).
- Divide by 3.1416 (π) to get your diameter, then use the Measure a ring tab.
