Movin On Estate Sales

Here we go again! I have no clue what to call this type of jewelry. Most all of it appears to be copper? Would it be considered Aztec? And again I’m sure you folks know exactly what it is. I put several sets together I thought was similar, along with a beautiful signed brooch with Dolphins and Turquoise stone. I can’t make out Artist name. See all pics. It’s a beautiful lot and again, all from same great local estate. She was a world traveler and bought only the best of everything.
