I only have some large long fashion jewelry chains, and I do have one that is about 6mm in a rolo style. I think 6mm would be okay if you were just using the 1 large pendant, but I think it is too wide for your small pendants. I really think 5mm would work much better. I like the 6mm on my chain which is about 36" and has a large pendant hanging from it. I rarely wear any jewelry that is not real, but I do like a few long heavier pieces. But even with just your large pendant, it is not heavy and more of a filigree type design, so I really don't think I'd go with 6mm for that piece alone, either.
