Vintage Sterling Silver Mexico Turquoise Cuff Bracelet 7"

For your consideration is a vintage sterling silver and turquoise cuff bracelet. It features a turquoise cabachon framed with sterling silver. It is marked sterling and Mexico along with a hallmark I am unable to distinguish. It measures almost 7". It came to me very darkened with tarnish and some remains along with some scuffs on front. A really cool piece though!
