Our Three Shades of Grey set was designed by Curt way before that dirty book came out. He has always said a man needs only three colours – black, white, and grey. When that book came out, our daughter called and said we had to change the name to Three Shades of Grey – so we did. Of course, these are all created using Swarovski Crystals and Sterling Silver. The necklace comes pre-made at 18″ and 20″ but we can make it any length you want.
