Silver-filled findings give you a fantastic look for a lot less money than sterling silver. Silver filled findings are a superior product to silver plated. Both consist of a copper-alloy core surrounded by a layer of sterling silver. The silver filled has a layer of sterling silver rolled over the copper alloy that is hundreds of times thicker than silver plated.
Silver filled findings have a much higher perceived value than plated findings. They still costs a fraction of sterling silver, and you work with it in much the same way you would with sterling. You can even solder them!
