Method 1:
- The Hands-on Method
- Grab a tape measure, length of string or strip of paper.
- Wrap it around the finger you'll wear your ring on—if you’re creating a ring stack, consider where on your finger the ring will sit—and mark the place where it joins.
- Lay your string or paper strip on a flat surface and use a ruler to measure the length up to the mark. Use the chart above to match the measurement to the closest ring size.
Method 2:
- Measure an Existing Ring
- Choose a ring that already fits your finger well.
- Measure the interior diameter of the ring in millimeters (mm).
- Use the measurement chart above to match the size of your ring to the closest size in mm.

The Diamond Details
Finding the perfect diamond shouldn’t be a guessing game.
With over 20 years of expertise, we take the complexity out of choosing a diamond, so all you feel is the excitement of finding the one. Every stone is hand-selected by our experts against the 4 C’s plus six additional quality checks, and every diamond is independently certified and ethically sourced.
Choose from two beautiful options:
Natural Diamonds
Formed deep within the earth over billions of years, a natural diamond is truly one of a kind.
- Certification: GIA, the world’s most respected gemmological laboratory
- Colour: D to G. We recommend F colour, exceptionally white and bright
- Clarity: VVS1 to SI1. We recommend SI1, with no inclusions visible to the naked eye
Lab-Grown Diamonds
Physically, chemically and optically identical to a natural diamond, created in a controlled environment, so you can choose a larger or higher-grade stone for your budget.
- Certification: IGI, the leading authority on lab-grown diamonds
- Colour: D to F. We recommend D colour, the whitest grade possible
- Clarity: VVS1 to VS1. We recommend VS1, visually flawless to the naked eye
