Sold by the piece, I was so thrilled to find these on my last buying trip! About 25x15mm, they have a reverse-painted rose under lucite with two drill holes, one at each end. You could make gorgeous chains or earrings from these pieces. Don't hesitate to pick up all you want, as we don't have a lot of backstock on these and I purchased everything there was....so we won't have them again. VERY rare.
