Found this silver bracelet in an old car. Can anyone tell anything about it? who made it? when? most of inlay has fell out, I think it was maybe shell? mother of pearl? Other than the "sterling 925 " and the "miguel 1040" I cannot read the rest. The gold and "I think diamond" ring looks like the markings "jd 417k" . Would that be right and what does it mean? Found it in old house on property I bought. I dont think they are very old.
