returns & exchanges

You have the right to return your jewellery until after 30 days of receiving it. It would be nice if you email us in advance (, but it's not strictly necessary.

You can return/exchange your jewellery in these cases:

  • your jewellery is flawed or arrived broken
  • it isn’t a custom made piece (check the item description what the standard size is)
  • it is undamaged and unworn
  • it is not a sample sale item (this will be mentioned in the product description of the piece if it's a sample sale item)
  • your item is clean and free of hair/other bodily things – Koi Atelier reserves the right to refuse returned items

Earrings can only be returned if completely unworn.

Shipping costs are the customer’s expense.

  1. Return the jewellery in the original packaging. If you don't have it anymore, please make sure it's packed securely so your item doesn't tangle, can't get damaged during transit, or get lost.
