I buy from Halstead as well and they have always been good. Never tried their gold beads . I've also never tried the silicone beads with metal beads and pearls ..So can't speak to whether or not they would show....though I think they might. Get some silicone bumpers and try them with a few small silver beads ( or whatever ) and your pearls and see what it looks like. I usually try things out before I order something expensive.
