Please keep in mind that the clasps are included in our measurements. To find the right size for you, we recommend measuring your wrist directly with a round tape measure. If you don't have any, you could try wrapping a shoelace or string around your wrist (or neck) and then measuring its length. Ensure that the measuring tape or string is not too tight. This will give you the exact size you need for selecting the perfect piece. If you're uncertain, opt for the next size up to ensure a comfortable fit for the bracelet or chain.
