A Guide to Diamond Engagement Rings

Ring Sizes

We use Australian ring size measurements, which are in an alphabetical range from A-Z.

As your fingers contract and expand due to the temperature, humidity, exercise, etc, your ring will fit on your finger tighter or looser. Your ring should fit comfortably and you need to find a balance between too big and too small. It is recommended that you should have to push your ring on tightly over your knuckle and it should spin slightly around the base of your finger. There should be some resistance when the ring is taken off – this will help to keep the ring on when your fingers are cold or wet. The correct size is the one that you feel the most confident and comfortable with.

We suggest that you size the finger you intend to wear your ring on at room temperature – this should provide you with a size that should be close to perfect most of the time.

Top-heavy rings can tend to spin on your finger, as the base of your finger is usually thinner than your knuckle. We suggest when sizing your finger for a top-heavy ring, that you err on the tighter side, rather than a loose fit. This will mean that the ring will stay on the top of your finger and it will ultimately be more comfortable to wear.

If you’re choosing a wide ring, you will tend to go up a size. There is more surface area on a wider ring and therefore more metal to grip to your finger.

If you are interested in a ring that is 5mm or wider, we suggest going up a size (one size larger than the sizing gauge). We suggest going up another size if the ring you are interested in is 9mm or larger (two sizes larger than the sizing gauge).

If you are buying a ring as a gift for someone, we recommend that you measure the inside diameter of a ring the person you’re buying the gift for, regularly wears on the finger your gift will be worn on.

MEASURING YOUR FINGER

If you do not know your ring size you can use this guide to obtain an approximate measurement.

Before measuring the finger on which the ring you’re purchasing will be worn, please ensure the following:

• Do not measure a finger when it is cold or too hot as this can have a significant effect on a ring size.
• Ensure that the size you choose has some resistance going on, and especially coming off, the finger.
• If you have a bigger knuckle and a thin part of the finger the ring will be worn on, the ring should be a very tight fit over the knuckle, to ensure that when it's worn it doesn't spin on the finger.
• If you have a smaller knuckle and the part of the finger where the ring will be worn is almost the same size as the knuckle, the fit where the ring will be worn should be tighter, as the knuckle will not stop it from sliding off.
• There are significant size differences between the right and left hand, so we recommend you measure the finger of the hand you intend to wear your ring on.
• To measure your finger you can use a tape measure or download our Ring Size Chart.

The number that lines up with edges of the opening is the ‘interior circumference’. Please note this number and then refer to our Ring Size Chart to choose the correct ring size.

If you have a ring that is worn on the finger you need sizing, print out the ring size guide (take care to print it at 100%), and place the existing ring over the circles. Measure the inside of the ring against the outside of the circle. If you can hardly see the black line which goes around each circle, you have chosen the right size. Compare the ring to the adjacent circles to check that you definitely have the right size.

You can then double check this measurement by measuring the inside diameter of the ring, and matching that against the ring diameter measurements shown.

Alternatively, if you don’t have a ring available, you can measure the finger itself to obtain an approximate ring size. You can do so by wrapping a piece of string or thin strip of paper around the finger on which you wish to wear the ring, marking it with a pen where it overlaps. Measure the piece of string with a ruler to obtain the circumference of the finger, and compare that to the European Size measurement shown on the chart. We would recommend that in order to obtain the most accurate measurement when taking your ring size in this way, you do so at the end of the day when the finger is at its largest, and not when your hands are unusually cold as this would lead to a smaller ring size.
