Can anyone give me any info on this ring? It was found in a plowed field near a 1800's farmsite that was abandoned in the fifties and razed in the 1970's. it vdi's in the low 70's so I am wondering if it is a copper gold alloy?? It was bent and my knee-jerk unbend reaction broke it.
Where it was bent the oxidation/corrosion crud flaked off revealing a much yellower color underneath. The rest is a deep coppery gold color. Could copper leach out after being in the ground for a long time? Could this happen to 14k? The stone (diamond?) appears to be single cut if that helps with the age guessing. Any info would be greatly appreciated. Thanks
