Gorgeous Marcasite Sterling Silver Bracelet

Gorgeous marcasite sterling silver bracelet. Worn once. Stamped 925. I believe the initials next to the 925 are "ML", but not sure. I've never seen a bracelet like this one. My sister purchased it on one of her many trips. The pattern around the back is so pretty. It's very secure snapping in with a latch and safety chain. My wrist is about 7-1/4" and you can see in the photos the space left when it's on. The diameter of the INSIDE of the bracelet is approx. 2-1/4". The last two photos show this bracelet with the other one I have listed for sale. They look great together.
