Each piece contains exactly 92.5% pure silver combined with 7.5% copper to provide the structural rigidity needed for functional jewelry. This standardized proportion ensures that the posts and hoops retain their shape without deforming with daily fastening.

Styles such as the MATILDE SILVER HOOP EARRINGS feature this official alloy with a hypoallergenic polished finish, preventing contact allergies in sensitive earlobes.

The flat-back push clasp on studs and the hinged or click clasp on hoops offer the best anatomical fit for reactive skin. The choice depends on the mobility your daily routine requires:

• Click or hinged clasp: Conceals the back tip of the post inside the hoop itself, preventing chafing while sleeping or exercising.
• Butterfly push-back clasp: Allows you to adjust the front gap over the earlobe to avoid excessive pressure on recent piercings.
• Continuous piercing hoop: Distributes weight evenly along the ear canal without protruding posts.

Both options guarantee direct contact between the skin and sterling silver 925, eliminating nickel residue.

All orders are shipped in an organic cotton pouch with an internal divider to keep each of the two earrings in the set physically separate. This fabric barrier prevents the metal from rubbing against itself during vibrations in transit.

The outer packaging includes a recycled paper card and protective envelope, shipped from our Madrid logistics center with delivery in 48 to 72 business hours.

Stud earrings minimize swinging and are the recommended anatomical option if you work with headphones or sleep with your jewelry on. Hoops, on the other hand, make more of a visual statement, but you need to watch the diameter and metal weight to prevent earlobe stretching.

For example, lightweight options like the AURO SILVER HOOP EARRINGS offer a medium-sized design with hollow profiles that balance structural lightness and visual solidity.

They come with an official 3-year warranty from the date you receive your order and a voluntary 30-calendar-day withdrawal period. The warranty covers manufacturing defects in the soldering, posts, or mechanical hinges of the clasps.

To process an exchange or return, jewelry must be kept free of visible signs of handling and returned with its complete original packaging.

The Blissou circular recycling program collects old pieces from the brand to melt them down and transform them into new collections, granting a 40% discount code for your next purchase. To benefit from the program:

• Gather any Blissou pieces you no longer use, whether or not they are damaged or mechanically broken.
• Request a pickup using the official form if you have accumulated five pieces within mainland Spain.
• Receive the 40% discount code, valid for one year and redeemable on items such as the CALIFORNIA SILVER HOOPS in our official catalog.

The recovered metal is transferred to domestic refineries that certify the responsible sourcing of the silver.

Standard delivery to mainland Spain, the Balearic Islands, and the Canary Islands takes 48 to 72 business hours after 24 hours of processing, with free shipping on orders over €40. If the basket total does not meet this threshold, the shipping cost is €3.99.

For Ceuta and Melilla, shipping costs €12.99, with the same delivery timeframe via Correos Express and online tracking.

Silver tarnishing can be prevented by storing each pair in a dry place free from ambient moisture when not being worn. The chemical reaction that darkens the metal is caused by contact with sulfur particles and the pH of sweat, not by wear and tear.

• Remove the earrings before entering chlorinated pools or saunas, or before showering.
• Apply perfume, body lotion, and hair spray before putting the pieces in your ears.
• Wipe the surface with a soft, dry microfiber cloth after each day of extended wear.

Storing the hoops separately in their original fabric pouch minimizes exposure to surrounding oxygen.
