Beautiful and unique crescent style neck base in 22K satin gold brass. Measures 4 1/2 to 5 inches. Heavy gauge brass, very sturdy....for your bodacious collage designs. This is what I used for as a base for the beautiful necklace centerpiece with roses shown on our home page on the Project Ideas link. Photo is a design from artist Renee Webb Allen. It is built on one of these crescent blanks.Sold by the piece.
