I can tell you that this is at least 25 years old if not older if was in my grandfathers trade chest, he owned a knife shop for over 30 years and would trade just about anything for knives or cash. This was in his collection. I do believe it is a real pearl. I do believe that it is set in gold or something that is called plated it has not tarnished and it’s been sitting in the same spot for at least 25 years because I remember this pendant, but there is no sentimental connection to this.
