The perfect dainty ring to wear solo or stacked! Made of pure recycled brass, these fair trade stacking rings are so cute, and they come in a variety of textures. Made from pure brass. Recycled metal, nickel free. Please note that brass reacts to the pH of your skin. It's likely to leave a green mark on your finger until it adjusts to your pH balance! Stay patient with it, and it will be a shiny and beautiful gold color forever and ever.
