My great-great-grandmotherin m30s work in New York City at Tiffany's she made these for my grandfather being our last name is Martins she was amazing as setting Stones because your hands are so small and I'm not entirely sure if she or co-worker actually made these they come back as 18 karat gold the Jeweler said it's probably over silver they weren't very rich at the time so I don't know also there's no markings so I think it was kind of done under the table as a present for my great great grandmother because they didn't have a lot of money. And they also had seven children to feed my great-great-grandfather was wounded in World War 1. I've take him to a few jewelry shops and Jewelers and they all say they're top-notch quality but unless they scratch him up real good they can't get through the 18th hair circus to tell if it is silver underneath but they said it's definitely not bronze and they're definitely very old and the way they look they look Tiffany made. My grandmother worked there 25 years as a jeweler making some of the finest pieces the world has ever seen she once wrote in her diary that she had set a 10 karat canary yellow diamond 4 Queen of England Incorporated by 128 Incorporated by 1 2 3 carrot diamonds all in Platinum when finished a way to proximately 2 lb and is this played in the crown jewels
