Vintage Aldo tiny black chips goldtone layered statement necklace

Aldo makes quality. The last pics will give you an idea of the material that is in the discs. It's some kind of stone that sparkles off lighting. There smooth to touch. It's very pretty with the black. There's 3 layers or rows above each other that sit as a perfect scoop style on your chest. The entire outline & chain is goldtone. Nice link chain & going from the far sides to back it's connected by 3 chains that connect as near the clasp ends. Measures 18.3" + 3". New
