Architectural Hefty Brass Bracelet

I have a small size 6 wrist and this bracelet is hard for me to get on. Once it’s on however it fits comfortably. It is a solid brass and very very cool. I didn’t weigh it, but if you would like me to just let me know. The two circles are soldered together so there is no movement. I bought it probably around 20 years ago at an AIA convention (Architecture). The circumference is 5.5 inches
