I recently aquired this from an estate of a local woman who passed away about 30 years ago through her daughter. I saw her around frequetly in the early 80's wearing this necklace. She was an astute collector of 1880-1930's Native American Baskets and Turquois Beads. This necklace stood alone in her belongings and I have not been able to find this mark so far in any database of marks.
All that I know for sure is that it is Sterling and the Bear Claws are authentic. It weighs 336 Grams I have no clue as to when or where she obtained it. Any information or opinion would be appreciated. My owntake on the mark is it looks like GM or CM but I could be wrong. Thre is no Silver mark on it that I can find but it is definitely .925.
I have photos but am new here and did not see an upload button.
