This is an exquisite Judith Leiber Marcasite brooch. It measures about 2.5 inches long. On the back are the initials JL and the words sterling vintage. Unsure of the exact age. The clasp is tight, but does not appear to have a locking mechanism. It is unclear to me if this was how it was made or if the clasp was broken. Nothing appears to have been broken off, and as I said, the pin/clasp itself is tight. No other imperfections are visibly noticed by this collector. The piece is in beautiful, preowned condition.
