Mattera is a Spanish design brand, with special attention to detail at every stage of the process. We work with suppliers and artisans committed to the quality of materials and the precision of the finish, so that each piece of jewelry is exactly what we imagined when we designed it.

All our pieces are made of 925 sterling silver and plated with 18-karat gold. We work exclusively with quality, nickel-free materials suitable for daily use.

With proper care, gold plating will retain its appearance for a long time. To preserve it, avoid contact with water, perfumes, creams, and sweat. Take them off before showering or exercising and store them in their pouch when not in use.

Yes. All our materials are nickel-free, the main cause of allergic reactions in jewelry. Both 925 sterling silver and 18-karat gold plating are safe for sensitive and reactive skin.

Remove them before showering, bathing, or playing sports. Avoid contact with perfumes, creams, and beauty products. Store them in their pouch or box in a dry place and clean them with a soft cloth when necessary.

We recommend avoiding prolonged contact with salt water or chlorine, as they can accelerate the wear of the finish. If they get wet, dry them thoroughly with a soft cloth before storing them.

Gently clean with a microfiber cloth or a jewelry polishing cloth. Avoid abrasive products or ultrasonic cleaners, especially on gold-plated items.

Store each piece separately to avoid rubbing and scratching. Avoid damp places and direct sunlight.

Sweat and natural skin oils can affect the finish over time. We recommend removing your jewelry before exercising and cleaning it regularly with a soft cloth.

We recommend applying perfume before putting on your jewelry and allowing it to dry completely. The chemical components of perfume can accelerate the wear of gold plating.

We do not officially offer this service at the moment, but if you have any questions about the condition of your jewelry, please email us at manager@matterajewelry.com and we will advise you.

Take a ring that you already use for your intended finger.

Measure the internal diameter with a ruler.

Compare the internal diameter of the ring with our size guide.

If your measurement falls between two sizes, we recommend choosing the larger size. Slightly looser rings are more comfortable for daily wear and easier to put on and take off. If you have any doubts, write to us at manager@matterajewelry.com and we will help you.

Don't worry. We accept size exchanges within the first 30 days from the receipt of the order, provided the item is in perfect condition and with its original packaging. Write to us at manager@matterajewelry.com and we will arrange it.

Yes. All Mattera jewelry includes a 2-year warranty from the date of purchase.

The warranty exclusively covers manufacturing defects and material failures. Any original problem with the part within that period will be addressed at no cost to you.

The warranty does not cover damage resulting from normal wear and tear, impacts, drops, improper handling, lack of care, or exposure to inappropriate products such as perfumes, creams, or chemicals.

No. Some natural materials may have veins, marks, color variations, or other small irregularities inherent to their origin. These characteristics are part of their nature and uniqueness, and are not considered defects covered by the warranty.

If you detect any issues within the warranty period, please write to us at manager@matterajewelry.com. We will assess the condition of the piece and offer you the most suitable solution.
