All of our jewelry is made using recycled 925 solid sterling silver. Our certified, nickel-free jewelry comes in 24k yellow gold plated, 18k rose gold plated and 14k gold filled and is certificated with the 925 stamps.Quality is essential to us, so we periodically do lab tests to check the metal purity and plating thickness in our production. As mentioned in the description, our earrings are made with sterling silver wire and a 24k gold plating. Do keep in mind that if you have sensitive skin and normally wear only solid gold jewelry, these may not be the best fit for you, I’m afraid. Over time, gold-plated jewelry tends to fade a bit with consistent use, exposing parts of the sterling silver underneath it. This might produce some reactions in sensitive skin.
