In addition to the precious metals Argentium sterling, regular sterling, & 14K gold in my jewelry,
Boho style sometimes requires the use of non-precious metals. Therefore,
quality gun metal, antiqued brass chain. and crystal studded spheres are used occasionally to capture the Boho look.
Do not polish, or wipe with a treated cloth, or dip in solutions any item that utilizes gun metal, antiqued brass, or the crystal spheres.
