This ring was my grandmother's and I think she received it in the late 1950s. I doubt it was new then.

It's set in platinum.

Inside the band is what looks like 8c7 and PLAT, no spaces between them.

Does anyone have any idea who might have made it, or what the 8c7 indicates? It's definitely not carat weight.

I already know this is a copy of a Bartolomé Murillo painting called The Immaculate Conception. I don't know how old it is or by whom, but the central figure has a more 19th century aesthetic than the original and the other copies I've seen in pictures.

I bought it at an antique auction in Glenwood, NY around 1978 or 1980, with no other information. In the same sale I purchased a landscape by Zygmund Lenduzcko. He was a Polish national who spent time in Brasil. I think both were from the same estate which just indicates that the auction location isn't much help in identifying the artist.

My dad had the opportunity to have it x-rayed, and at that time (mid 1980's) they could tell there was a different image painted over underneath this one but I don't think there was any idea what it might be.

I'd like to identify the artist if possible.
