Womans Bracelet - Sterling Handwrought with a Mark

[iriss112]

I've looked through the categories of the main site and I'm not seeing any marks that match the one on my bracelet. I'm really hoping to find out more about it, mostly where it came from! It used to be my mothers, but she passed so I can't find out any details from her. The bracelet is very stiff, hard to stretch open and closed, so possible plated, but I really don't know much about that stuff. Hopefully these images help, let me know if you have any ideas where this may have come from!
