Size table

Describe the dimensions of the jewellery you imagine in centimetres or millimetres. This will help us calculate the approximate weight of gold needed for its manufacture.

Size

In the table, we have presented the inner diameter of each ring size and the corresponding European size (the size number corresponds to the inner circumference of the ring). For us, the only accurate method to determine the correct size is the use of jewellery measurements. All other methods we have tried result in minimal to significant deviations.

If you have a ring that fits, measure its inner diameter with a caliper.

*For orders we have already taken, we can provide and send jeweller’s measurements for you to take an accurate measurement.

If you have any questions, feel free to contact us for assistance.

Choosing a bracelet length is important, as most bracelets are difficult to shorten and lengthen. Below, we have outlined the recommended steps to help you determine the right length for your wrist.

How to measure correctly
  1. Use a tape measure. If you don’t have one, you can use a thread or ribbon.
  2. Wrap the tape measure around your wrist where you will wear the bracelet.
  3. Mark the length on the tape measure or on the thread, cord, or ribbon you are measuring with.
  4. Add 2.5 cm to this length for a comfortably moving bracelet. We do not advise adding less than 2 cm.

If you have a bracelet that fits perfectly, measure its length including the clasp.

* Note that there may be a slight difference between your left and right wrist.

The choice of necklace length may depend on the characteristics of your body and the features of the jewellery. As a guide, we have graphically depicted the standard lengths of chains to help you visualize your options.

This classic tennis bracelet with diamonds is a must-have for the sparkle lovers! At Efirgems, we strive to bring you the highest quality, which is why our diamonds, with a total weight of 0.86 carats, are VVS/E quality. The bracelet is Italian made, 18k white gold, and the stones are hand set by our master jeweler. The length is 16.5 cm.
