I own a ring that had the same patina from CVB. It’s a paint as you said. Mine started coming off after a jeweller cleaned it in an ultrasonic that had ammonia in the cleaning water. I decided to remove it by soaking it in ammonia myself. Came right off. The ring looks even better imo without it. Before that the treatment lasted 3 years. So it isn’t so delicate if you avoid ammonia and apparently steam.
