Vintage cheapest Floating Opal Gold Filled Bracelet, Crushed Opal Cabochons, Amco Jewelry Co., October Birthstone Birthday Gift

Vintage gold filled floating opal/crushed opal bracelet. Measures 7" long. This bracelet has three 3/8" x 5/16" cabochons of crushed opals, frozen in clear Lucite alternating with four 3/4" filigree bar links. I don't think these are in liquid like some are, I can't see them moving, but they are stationary in the Lucite material. It is in very good shiny vintage condition. Marked cheapest 1/20 14k AMCO on the hangtag.
