VINTAGE NATIVE AMERICAN SIGNED STERLING SILVER & BLACK ONYX CABACHON RING

Unique vintage sterling silver ring set with large black onyx gemstone cabachon. This ring has ornately designed prongs that hold the stone. Piece is stamped on the back with JLT and a buffalo, this is the hallmark of the maker of this ring. Ring is a size 6 and is in overall good condition, however there are scratches on the onyx stone that I couldn't quite capture in the pics.
