Antique citrine glass stone dress clip, the stone is bezel set in brass and the design of this clip is unique and unusual. Early Victorian? Quite possible. Measures 1 3/4 in. long and nearly 1 in. wide. Front is in excellent condition with the back having some expected wear. The facets on the stone look like what a genuine stone would have. I'm not a gemologist but do know a little about the cut of stones information I got from a jeweler.
