Repairs & Warranty

Mociun offers a six-month warranty that covers the cost of all repairs under normal wear for the first six months after purchase. However, if pieces are noticeably bent, show improper care, or are damaged in any other manner, repairs will be performed at cost. We offer cleaning and stone tightening on all Mociun pieces where the first service will be complimentary and any servicing after your first service will be at a charge of $35. Outside of warranty, Mociun will perform repairs for a fee. Please note, if any jeweler other than Mociun makes alterations or repairs to your jewelry within the first 6-months, the Mociun warranty will be voided. We are happy to make minor adjustments to jewelry, including resizing, for an additional fee. For international clients, there may be a local option for repair with trusted jewelers in your region.

To initiate a repair, please complete our Service Request Form. Our repairs team will be in touch upon receipt and review of your form. All shipments sent to Mociun require prior authorization. Shipments sent without prior authorization will be returned to sender. Shipments must be carefully packaged to ensure that items are not damaged in transit. Mociun does not cover shipping costs. We recommend fully insuring all shipments. Please contact your insurance provider to ensure that your shipment is protected and determine your best shipping option.
