Refund policy

Warranty
All Mar de Luna jewelry is covered by a warranty against material and manufacturing defects for 24 months (2 years) from the date of delivery. Our pieces are crafted from high-quality, durable materials, but they are not indestructible and require proper care.

Impacts such as hitting or lifting solid and heavy objects can damage your jewelry and may cause gemstones—including diamonds, emeralds, and sapphires—to crack, loosen, or break.

Manufacturing defects do not include normal wear and tear, scratches, misuse, or damage caused by accidents or improper handling. Discoloration due to contact with harsh chemicals, deformities, lost center stones, or damage caused by external impacts (e.g., hits, dents, pressure) are not covered by the warranty.

Likewise, jewelry must not be altered, handled, or repaired by any service provider other than Mar de Luna, as this voids the warranty.

The warranty applies exclusively to the original purchaser and is non-transferable.

All warranty claims are subject to verification by the Mar de Luna team. The item must be evaluated and classified as defective by our production department. If a warranty claim is approved, the appropriate solution (exchange, repair, or other) will be determined on a case-by-case basis and discussed with the original purchaser.

Exchanges & Returns
Mar de Luna accepts exchanges within 30 days of delivery. All purchase decisions are final, and we do not offer refunds. 

Jewelry pieces must be in perfect, unworn condition, free from signs of use, damage, or alterations. All items must be returned with their original packaging and documentation.

For engagement rings, size adjustments or modifications will be evaluated individually and may incur an additional cost.

Please note that all shipping costs related to exchanges or warranty evaluations are the responsibility of the customer.
