Two are the same complex pattern, one has a surface stress line which I didn't notice for years, I thought it was part of the marbling. It's the one with the lighter marbling. Both bangles measure 15/16" wide X 2 9/16" wrist opening X 3/8" wall thickness.
The knob carved bangle with brass accents measures 3/4" wide X 2 9/16" wrist opening X just over 3/8" wall height.
Excellent condition with the exception of the stress line on the above mentioned bangle
