Made with gold tone tarnish resistant copper wire, gold tone laser cut charms, gold tone chain, and peridot. Ear cuff bases are easily adjustable to your ears and can even fit kids. The heaviest ear cuffs weigh about .4 oz or 8 grams. The ear cuffs come in pairs, so you will receive two (one for each ear). You do not need any piercings to wear them and since they do not go inside of a piercing, a lot of people who have metal allergies can wear the ear cuffs with no problem. Please keep the ear cuffs away from water and store them in a dark place like a jewelry box.
