We have a 60-day exchange policy for defective pieces. Send us an email at info@delicaciesjewelry.com explaining the issue and attaching a picture. We will likely ask you to ship the piece back (don’t worry, we will provide a postage-paid label!) so our jewelers can take a closer look. We will also send you a replacement piece immediately.  For background, we get our chains and jewelry “findings” (clasps, jump rings, etc) from manufacturers who provide specific pieces to jewelry companies. Though our suppliers make very high quality pieces, unfortunately at times defects occur in these tiny pieces that cannot be seen by the naked eye. We’ll always do our best to make sure you are happy!
