This heavy old bolo is 5 1/2 inches long, 4 inches wide, and weighs 150 grams. Claws are inlaid with coral. “Handmade” and “Sterling” are stamped on the back. Hallmark appears to be a fish with 3 crosses or T’s inside. The turquoise is a gorgeous deep blue-green. The arrowhead is shiny black, I’m guessing jet or onyx. I’d appreciate any and all information.
