Gemmyo covers all repairs under warranty. For any other issue, our workshop will provide a quote before proceeding.

If the repair is due to a manufacturing defect, we will take care of it entirely, including return shipping.
Please note: this warranty does not apply if the piece has been altered outside of our workshop.

If your ring doesn’t fit quite right, don’t worry, we offer one complimentary resizing within 30 days of delivery, for orders shipped from the European Union or Switzerland. For our pendants and bracelets, resizing is done on a quote basis.

Simply contact our customer service at hello@gemmyo.com to arrange the return. Depending on the model, the resizing process takes between 4 to 6 weeks. This service is offered once per ring.

Your piece will be carefully packaged to ensure it reaches you safely.

To keep it in perfect condition, we recommend storing it in its pouch or box when you're not wearing it or while travelling.

Try to store each piece separately to avoid friction and reduce the risk of scratches.

We actually have three box sizes.

First, a case adapted to our ring models and most of our earrings, its dimensions are: 6 cm x 6 cm x 4.5 cm (L x W x H)

We also have a second larger case for our wedding bands, pendants and bracelets the dimensions are: 8 cm x 6 cm x 4.5 cm (L x W x H)

We have a last case designed for bracelets of ring type, the dimensions are: 9 cm x 9 cm x 4 cm (L x W x H)

It is also possible to receive a piece of jewelry in a small cotton suede bag, in very rare cases, if for technical reasons a piece of jewelry would not be sufficiently supported in our classic box.

If you have any questions about the size of our cases, please do not hesitate to contact us directly.

We’re happy to offer a professional cleaning service for your jewelry, free of charge and as often as you like.

This service is available exclusively in our boutiques. Feel free to drop by or book an appointment, it only takes about 10 minutes.
