I own a plain silver ring that distinguishes itself with a tiny silver disk where one normally sees a solitaire stone ring. In the center of the little disk, there is an imprint showing a very tiny dark square. In the center of this square, if one holds it up ( on the side that is not known to me as right side up or upside down), there is a typewriter size, slightly raised capital G , ( but with not as much accuracy as that). I have wondered, since the time of my having purchased it, whether this appearing- to- be G is the hallmark of the artist or designer. This is a real cool website that I just signed up for. I would appreciate any replies to be offered.
