I bought a piece of jewellery and it is too big, can I exchange for another size?

Yes, of course, we can. If this is completed within our 14 day policy then it is no problem as long as the item is still in stock. Please can you fill out the exchange and returns form and send over to creations@blackandsigi.com.

If there is an enquiry outside the 14 day policy, it will be dealt with on a case by case basis.

I’m unsure of what size I am, can you help?

Under each product, where a size needs to be confirmed, you will find an explanation of how to measure your size appropriately.

For bangle sizing, we have 4 different sizes S (19cm), M (20cm) , L (21cm) , and XL (22cm). The way we can gauge what size you will be is by tucking your thumb into your palm, and measuring around your hand knuckles. You can either measure using a soft tape measure or using a piece of string then using a ruler.

Alternatively, if you have a bangle already that you know fits well, measure the diameter from inside edge to inside edge. Compare this measurement with our table to work out your size.

S – Hand Circumference 19cm / Diameter

M– Hand  Circumference 20cm / Diameter

L – Hand  Circumference 21cm / Diameter

XL– Hand Circumference 22cm / Diameter

For our ring sizes  we have 4 standard sizes S, M, L, XL. The first step is to measure around the largest part of the finger where you would like to wear our piece. This is often either the knuckle or the bottom part of the finger. Then take this measurement and compare to our charts.

Alternatively, if you know your ring size, we also reference this on the size guide for ease.

Finally, you can measure the diameter of a ring you already have to reference your size.
