Hi All, I recently made a 14k white gold wedding ring and I oxidized it by heating it up on a hot plate and dunking it in hot liver of sulfur many times. I built it up to a nice even black color and I buffed the higher areas of the design down to the gold. I gave the ring to the client and he went in the ocean with it a day later, and he said the black patina washed off right away. I’ve since also tried Griffith Silver Black on it and torch heated the piece before dunking it in the solution. I did this several times and it became halfway blackened but not an even finish. At this point I’m out of ideas, but if anyone has successfully oxidized 14k white gold with a long lasting finish I’d love to hear what you did!
