This necklace is designed by Rebecca Minkoff gold-tone and black enamel blade necklace.  The necklace is adjustable at about 20 1/2 inches and 21 inches long. It could be even smaller if the hook is placed into the larger loops. The 'blade' is about 2 3/4 inches long and about 1 1/8 inch wide (not including the gold-tone Y shaped piece.  It is in excellent, used condition. The necklace is labeled, as you can see in my pictures.  A-2092-1999-FS
