Looking for some info on this TAXCO HA 940

I’m an estate liquidator and recently purchased a lot of very nice antique silver pieces. This one has the hallmark: TAXCO HA 940. It has 19 separate panels, linked together with a hook and loop design, decorated with cabochon amethyst. Measures overall 16" long

Any info anyone can provide would be appreciated such as: is it a necklace or would be used as two separate bracelets? Age? Value? Thank you all!
