Chunky Silver Artisan Cuff Bracelet

Vintage 1970s lost wax cast bracelet with a chunky design. It has three free form figures. Measures 1 3/8" wide. Interior measures 4 3/4" plus the opening of 1 1/4". It weighs 92.9 grams. I acid tested it and it is not sterling silver. It may have silver content under 925 as it is very tarnished, looks and smells like sterling. My acids don't test for silver content under sterling so we can only guess. No hallmarks.
