Hello! I have a cuff bracelet that has a huge chunk of 18k applied gold on a sterling silver base cuff. The back is marked Copyright, a symbol that looks like a BP with a line accross the top extending past the B, Sterling 18k. I have seen and found MANY very similar cuffs that led me down different paths but I have not yet been able to identify this cuff’s maker. I have books, utilized forums, websites, and still nothing. I asked a high end Native American jewelry dealer in Brimfield Massachusetts at the antique show and still nothing! I love and cherish this bracelet but would just love to know more about it. ANY help would be greatly appreciated!
