This 2-1/8" x 1-7/8" brooch is cast in Argentium Sterling Silver. It is finished in a matte, sanded finish that will remain almost completely tarnish-free. The joint and catch on the back are carved as part of the brooch, rather than soldered on. Quinn's "mouth" is filled with a subtly-sparkly quartz beach pebble from Nerja, Spain. His "eye" is blue chalcedony. He would make a cheerful and faithful friend!
