Because we use solid 18 karat gold across our Fine Jewelry line, you can wear your piece day in and day out, including in the shower, with never any worries about skin sensitivity or oxidization. As a precious item, though, this piece deserves the utmost care. This includes avoiding direct application of perfume, lotion, or other household chemicals, removing it before entering chlorine-filled water, and cleaning it periodically. When storing your solid gold piece, we recommend clasping it shut as if it's being worn, to avoid knots and tangles. As a reminder, solid gold is not scratch-proof, so be mindful of how your pieces are treated during everyday wear and avoid wearing it during activities that could damage your pieces such as strenuous exercise or other heavy-duty tasks. Dulling can rarely occur over time but your piece will never fade or tarnish; feel free to use a cloth and warm water on your piece to restore that beautiful shine. *Please note, while waterproof and sweatproof, that Qur'anic pieces should always be tucked away or removed prior to entering the restroom.*
