12K/20 GF Vintage Art Deco Rhinestone Interlocking "Chain Bracelet! EXQUISITE!

This is truly an exceptional vintage bracelet with a band that is work of art! The bank has rows of interlocking gold rectangles (the band is marked on the clasp 12K/20 GF. The center has a raised , almost a buckle design, with aqua blue rhinestones on the edges and a center with two rows of inset sparking crystal rhinestones on either side. The design is so similar to Crown Trifari and Mazer designs, but unsigned and I don't know if either used 12K for their pieces. This bracelet is in excellent vintage condition with no damage that I can see anywhere. The entire bracelet measures about 6 3/4" from end to end and 1 1/2" from top to bottom in the center.
