This is a hard to find charm for sure!
I have never seen this before, it’s reverse carved and the background glows a bit like mother of Pearl or some sort of material that catches the light. I took photos with lights on and off so you could see what I mean!
The back isn’t marked, and has a little bump sticking out, very slight, and tried to photograph it, must have been made in manufacturing.
The little loop hanging on it says Lestage sterling, I assume the outer bezel I sterling too, but that part is not marked.
The charm is 5/8” across, and 7/8” tall including the bail and the loop.
Please ask if you have any questions! I am hoping some fan loves this or finds it for a gift!
