I think this is a buckle; it is meant to be sewn on temporarily I suppose because it has 4 openings on the back. The stones are paste and all original with the exception of one which is darker than the rest; of course it may have just darkened. I bought this initially years ago to make a pin out of it, but never got around to it. The piece is in superb condition and measures over 3 3/4" wide and 2 1/2" high. The stones are deep blue and topaz.
