Vintage white 13th century and jazz age white bracelet

This jewelry style dates back to the 13th century and very popular again in the 1920s jazz age. I put a snap shot of a little history description of enamel jewelry and why it can be so expensive and this one looks to be a desired denning signed piece similar to the last picture snap shot of where I circled a similar one of hers and the way she’d sometimes sign it.
