This is a vintage "Givenchy" piece, probably 15-20 years old. It opens aat the top where the bracelet is 1" wide. It tapers down to 1/2" in the back at the hinge. On the top ribbed metal piece the ribs or ridges alternate between silver and gold toned metal, so it can be worn with everything. The lucite has a slightly yellow cast to it in certain lights because of the gold toned metal underneath the top emetal pieces. The bracelet is slightly oval in shape with inside diameters of 2 1/2" side to side, and 2" top to bottom. It is in excellent condition, and marked, as shown.
