We use 24k gold-plated chain that has been through a proprietary coating process that prolongs the life-span of the piece. Our other metal components are 24k gold-plated or 14k gold fill. For these materials, do not use any specialized jewelry cleaners.  We've found it best to wipe down the pieces after you've worn them with an alcohol-free, lotion-free, wet wipe (like a baby wipe) to remove sweat and dirt residue before storing it in the EDEN + ELIE jewelry box provided with your order or a similar padded box. You will want to keep it out of strong sunlight.For our leather bracelets, we recommend storing them in a cool, dry place. Use a cotton or microfiber cloth slightly dampened with water to wipe off any dirt residue before blotting dry. We treat our copper clasps and trims with a coat of jewelry shield which protects the material and keeps the color from oxidizing.
