Sisters Necklace - Big sis - Middle sis - Little sis - Hand stamped Sisters Jewelry - Three sisters - Puzzle piece necklace. This listing is for THREE Necklaces. Being three sisters ourselves, we simply had to make this piece. This necklace consists of a 1.5" stainless steel heart broken into three puzzle pieces. We have hand stamped on each piece "big sis", "middle sis", "little sis" in our custom font. Each piece hangs from a sturdy stainless steel chain. Your necklace will not tarnish or change color.
