What does the group think of using one of those canisters of compressed air used to clean computer keyboards as a method to clean a diamond in a typical prong setting with platinum? I did this to my e-ring once or twice after cleaning it with Sparkle and then steam cleaning it. I waited until the ring was no longer hot from the steam. In fact, I waited a whole day before using the canister. Still, I noticed how cold the stone and the metal got after the air pressure cleaning. Is this dangerous for a diamond?
