Find Your Ring Size
Method no. 1: Measure your own finger
Found the perfect ring? Follow these instructions to find your perfect size.

Step 1:Β Measure your finger by wrapping a strip of paper or wide tread around it, leaving enough space to slide the ring over your knuckle.
Step 2:Β Mark the place where the paper strip meets and measure the length by using a ruler.
This is the circumference of your finger, which corresponds to European ring sizing. E.g. if it measures 5,4 cm you should choose a size 54. If you fall in between sizes, we recommend that you chose the larger size.
As a rule of thumb, you can always remember that you will probably need a slightly bigger size is if the ring is wide versus slim. If the ring is sleek and slim we recommend that you opt for a lightly smaller size eg. 0,5 size difference.
This method can be used to find the ring size of any of your fingers.
Please note that the ring size can vary depending on the ring design and fit on your finger.
Method no. 2: Measure your own ring
A helpful method if youβre surprising someone with a gift orΒ treating yourself.

Measure one of your own rings using a ruler. Lay the ring on a flat surface and place a ruler on top of the ring. Measure the ring (inside diameter) on the widest part of the ring. When it comes to selecting the perfect ring size, precision is key, as even a few millimeters can make a difference..

Find your Bracelet Size
Measure yourself for bracelet sizing
To find your bracelet size, you can measure your wrist size or a favourite bracelet that you already have!

1. Measure your wrist size
Step 1: Wrap the tape measure around the wrist bone, so that it fits snugly without feeling too tight or too loose.
Step 2: Mark where the tape measure overlaps. This is the exact circumference of your wrist.
Note: You can substitute the measuring tape with a string or ribbon and use a straight ruler to measure the length from the point of overlap to the end.

2. Measure the length of a bracelet that fits well
If you already have a chain bracelet that fits right, this is how to substitute wrist tape measurements with the bracelet chain length:
Step 1: Open your bracelet and place it on the table
Step 2: Using the centimetre/inch edge of a ruler, measure the length of the bracelet cord/chain from the outer edge of the clasp to the other end of the bracelet.
Note: The flexible tape measurements are the circumference of your bracelet. To convert circumference to diameter, you can divide the millimeter (mm) Circumference measure by 3.14 (D = C/3.14) or use an online converter

Necklace Size Guide
The Long and the Short of It
Necklaces vary by chain length. The circumference of your neck and size of the pendant will impact how your necklace sits on its own and with other styles.

1. Cut a piece of string to the length of the necklace youβre interested in.
2. Wrap the string around your neck to see how it sits. Achieving the right balance is crucial for layering, so take into account the size and shape of the pendant.
3. Try this again with necklaces of varying lengths to see how they might look when layered together.
