Rare large turquoise cabochon revealing a lot of host matrix and water webbing, with a luminous blue gemstone set in a serrated bezel. Surrounded by silver rope and a 3 1/2" X 2 1/2" master full heavy silver offset. Half circles that flow around the setting like dolphins. Lots of motion finished off with raindrops. Original patina. No marks. Old pawn? It will accommodate a 1 5/8" width strap.
