Ring Sizes

Ring Sizes by Julie Nicaisse Jewellery Designer in London

The best and the most accurate way of finding out your ring size it is to visit your local jeweller.  However, when shopping for a ring online or perhaps when buying a ring for someone else, you do not have the advantage of professional advice.  If you wish to purchase a ring online and are unsure about your finger size, we suggest that you order a DIY ring sizer and follow the instructions below on how to use it, alternatively you can e-mail info@julienicaisse.com to arrange a sizing appointment.

Online order

Please make sure you select the correct ring size when ordering online.  Rings ordered in a specific size, can be sent back at your own cost for a free adjustment of 2 sizes bigger or smaller. For all other size adjustments, we will charge £20+postage.  Please note that once a ring has been adjusted to your specific size it cannot be exchanged or returned.

Buying a ring as a gift

You are welcome to send us an old ring provided it is worn on the exact finger and hand as the intended new ring so that we can measure it for you.

When ordering a ring online please select “standard size – gift” in the drop-down menu.  These can be sent back to us for a free sizing (note you will be responsible to pay for the postage).

Order a DIY ring sizer and use while he/she is deeply asleep (see the instructions below).

Using the DIY sizer

Make sure you measure your finger at the end of the day when the finger is the largest; do not measure a cold finger as this is when fingers are at their slightest.

Ensure that you are measuring the exact finger (and hand) on which the ring will be worn.

If you are purchasing a wide band, please increase the size by +1 size.  Ring sizers are usually made for thin band.

The ring sizer works like a belt.  Push the end through the buckle to form a ring shape.  Put the ring sizer on your finger and adjust to give a comfortable fit.  The arrow will indicate your ring size, if the arrow points to a line, that indicates it is a half size.  Your ring sizer should be snug enough not to fall off, but also loose enough to slide over your knuckle, the degree of which may vary depending on which finger the ring is meant for:

Ring and middle finger:

The knuckle is usually bigger than the base on these fingers, so the ring needs to slip quite snuggly over the knuckle.  This is why it is usually a bit more difficult to take a ring on and off these fingers.

Pinky finger:

The ring needs to sit as tight as possible but you also need to be able to bend the finger.

Index finger:

It is the opposite for the index finger, which is usually a bit fatter at the base, so make sure to size “up” (about + 1 size) to allow your finger to bend.
