ADDITIONAL INFO ABOUT DOUBLE CLAD GOLD FILL:
Gold filled double clad sheet metal is the very finest alternative to solid gold that you can purchase. It's made to be much more durable than plating and is PERFECT for people with metal allergies. Double clad gold filled metal is made by thermally bonding real 14k gold to each side of the base metal in a thick layer that enables you to wear your jewelry without fear of discoloration, allergic reaction or scratches. In fact you can wear your gold filled jewelry in the water.
