NWOT VINTAGE Amber like Austria bangles bracelets

NWOT VINTAGE Amber like Austria bangles bracelets These are NWOT but have so many scratches and marks on the gold edges. Sorry I didn’t store this properly. It’s very lightweight. I think it’s a type of plastic or resin (lucite? Acrylic?) that was popular then (especially chic from Europe). The “inlay” looks like amber: opaque, dark orange-brown amber colour, with cream-black inclusions. Inclusions look like they are suspended in the “Amber”. Original manufacturer tag: made in Austria. Vintage. C 1970s. 2.5” inner to 3.25” outer diameter, 8 mmx13 mm Black colour and double set are available
