Silver Mexican Minimalist sodalite ring

Minimalist Mexican Silver sodalite ring VERY MINIMALIST MODERN x rustic industrial. Nothing is slick and overly shiny. You can see the seams in the setting and the folds in the metal band. The silver is shiny but you can see shades, tones, and soldering marks! The simple marquise shape fits so perfectly inside the setting. The only other detail is the split band. New. Vintage c. 1970s-1980s. Hallmark: “TAX??” & “925 FMC”. The first word might be “TAXCO”. Probably handmade and / or polished in Mexico. Size 7. 20x7 mm stone 3 mm deep setting Almost 2 mm - 7 mm band, slightly over 1 mm thick. It was quite tarnished so I used some toothpaste to clean it up! 🪥 J.R.R. Tolkien fans: looks like Sauron’s Eye but opaque blue! Maybe it’s Dark Galadriel’s Eye! 👀🧿👁️👁️‍🗨️
