Hi, I am new here and wanted to ask a question about a quality stamp (s) I own. It says Belais 18k. I bought these from a private home sale. The basement was full of jewelry machinery and tools and since I was a starting jeweler at the time I bought some old burs and stamps. This was in New York. I remember asking the grandson that if I were him I wouldn't be selling all this stuff because it was just amazing and part of his family. But when I got back I looked at the stamps and saw it said Belais 18k. I just read about the Belais brothers bring the first white gold to america and I even believe I have a antique ring in my family that says Belais. I couldn't imagine I purchase this from the Belais family itself? Does anyone have any information where David made his jewelry? Because I know about the location (home) I got the tools. I rarely set diamond jewelry and I am more into Turquoise and other semi precious raw stones so I would never use the stamps and don't have the expertise to even make diamond jewelry so it's really something I like more information about. I had the stamps appraised at one point but I just sent in the picture of the stamp and markings.
