Sliced from a silver plate on red brass or bronze tray. I believe this was made in the middle of the 20th century based on style, but I was able to find very little about this.

This will fit a 6” to 7” wrist.  

Sizing Directions:

Gently wrap a piece of ribbon or string around the part of your wrist you would like to wear the bracelet. Mark where the ends meet and lay it along a ruler. 

 You could also use a cloth tape measure if you have one.

Bracelets generally follow these sizing  guidelines and hand adjusting may be needed for best fit.
