Super looking lot with 3 original 1920s celluloid and rhinestone flapper bangles, as pictured.   
The sapphire-blue and the clear rhinestone in silver painted bangles are each 2 rows, and the amber rhinestone bangle has 3 rows.
The silver and clear rhinestone bangle is a hair wider, 3/8" and the blue and amber bangles are each 5/16" wide.
The amber bangle has 2 missing stones and a number of other darkened stones.   No missing in blue or clear bangles, but again some maybe a little darkened from age.   No cracks or breaks.   Whether worn together, alone, stacked with others, they are fabulous century old bracelets!
