What Warranties do you offer?

At MADU we offer 1-year warranty due to the high quality of the materials we use and the great hard-work that goes behind the scenes.

During this 1 year of warranty, you may send your piece back for repairs or re-cleaning if necessary. This does not include damages caused by misuse, attempted repair by third parties, modification, wear and tear and natural aging that the jewelry suffers with use, as well as errors when following the instructions for the care of the items.

In the case of this, please email our customer service email at to schedule a jewelry cleaning appointment or to ask us questions.

You may come by the studio or send it via mail to have it re-polished and cleaned.

What materials do you use in your jewelry?

We make sure to be as transparent and responsible as possible in our practices. Therefore, we source our metals from reliable sources that certify it is recycled (sometimes known as ECO-silver) or mined fairly.

We want to supply you with the best quality stones, so we make sure that the stones we use are certified Swarovski Zirconia stones. Swarovski Zirconia is not a synthetic diamond, but it is commonly known as a diamond imitation due to its high quality, durable, hard and optically clear synthetic crystalline substance.

Yes, the sterling silver we work with is recycled and nickel free. If you would like to know more about the materials we use please go to the Creation Process Page.

Can I customize a piece I found on your website? What about a ring I found somewhere else?

Yes, you can customize it with some different colored stones we have in stock, but please reach out to our team to see the available options. At the moment we don’t make customized designs beyond changing the color of the stone in some designs. (check the item you are interested in to see if they are available for customizations directly in the product page)

We do not copy designs from other stores as it is illegal to copy other artist’s work.
