White and gold beaded clasp bag with gold chain

White and gold beaded clasp bag with gold chain. There are a couple of missing beads, but it's hard to tell, and there is a stain on one side that is only visible at very odd angles to my eyes? I've tried to get a good picture of it here. I'm sure there is a way you could clean it, but I don't know how to treat bags like this and didn't want to ruin anything.
