I've been looking at the posts on this forum and it seems the 3-prong (esp "martini") settings are popular for earrings these days. I know I want mine to sit pretty flat and I'm thinking 3-prong will look rounder and cleaner. But a jeweler I talked to seemed a bit hesitant. He said he'll do whatever I want but he feels 4-prong would be more secure. Do you worry about your 3-prongs? If I get platinum, I would think it's going to be strong enough that you wouldn't lose a prong, wouldn't it? BTW, I'm not going as large as some of you ladies...probably half carat or so in each ear. Thanks for any advice.
