Ring size-conversion

Greek Jewelry Shop offers rings in both US or European mm sizes. Most rings we make are manufactured to order, so its no trouble at all for us to give you the best fit possible. If you're American, you'll also be pleased to know that we will manufacture your ring to the closest half size!

Ring sizing is FREE when you order a silver ring from us and the size option exists on the product page.

The chart below is useful if you want to convert from another sizing format (eg. UK) or if you just want to cross-check your size.

Not familiar with US or EU mm sizing? Not a problem. Use this chart to find the nearest size in European mm or in US standard sizing so you can place your order with us.

- Please note that the smallest incrediment on our site are  US half sizes or whole mm circumference sizes (eg. 54mm, 55mm etc).

- If converting and in doubt in doubt between which to use, we recommend mm as the increments are smaller leading to more accuracy. 

Once you have found the ring that brings out the true Greek god or goddess in you, head over to the product page and select the size that is nearest to yours EU or US in the drop-down selector.

Tips on sizing: On the whole if you have found a ring that you like and find inspiring, sizing shouldn't be an important issue to stop you from purchasing a ring provided you have some idea of your size. Re-sizing (within proximity) is usually very inexpensive to request locally by any jeweller in your area. If in doubt or in-between choosing between 2 size increments, then it may be wise to chose the smaller one as it is a lot easier for a goldsmith or even a jeweler in your area to enlarge a ring rather than to size it down.

(A ring can easily be sized up by a couple of metric sizes (or half size in US) with the correct equipment in less than 5 minutes and will incur just a small charge (or possibly none at all), however sizing down a ring that is too large may mean a little bit more work).
