Our pieces are handmade by Olivia in Paris with natural non-allergic material. Guaranteed without nickel. Some pieces are more fragile than the others and may require a slight maintenance. We advise you to store them separately in a dark and dry place, and to avoid wearing them in hot, damp places such as hammam or sauna. Jewels made with 925 sterling silver can slightly oxidize. Many silver cleaning products exist, but we suggest to use tinfoil and bicarbonate in a bowl of warm water to avoid toxic waste. 14k gold can turn slightly pink because of its copper components: we advise you to softly brush it with a sponge and plain soap. Gold and silver-plated pieces can undergo the same treatment. Bronze plated jewels can leave slightly green stains on the skin depending on your sweat’s acidity. These stains are due to a natural process and won’t trigger any allergies. They are easy to remove either with makeup remover or natural soap.To maintain or purify natural stones with a salted bath, do not put salt directly on metallic parts: it might deteriorate the setting permanently. Don’t hesitate to reach and ask us any question, especially to fix your broken good.
