Like the little black dress, sometimes less really is more. I may not have contemplated color, shape, and material combinations with these, but it is still fun to put together something that is beautiful in its graceful and elegant solo presentation. These do not necessarily fall into the 'one and done' category. I may well repeat these IF I can get the same elements. But because I can't always be guaranteed of that, most, but not all, are sold as a set of necklace and earrings.
