This is a Martha Stewart project from a couple of years ago, but a good one to keep in mind.
They describe it as project for repurposing an old prom necklace etc. Nice idea! But I would suggest taking their second suggestion and sewing the necklace to the fabric rather than gluing it. You never know how fashions might change and you might want to wear your old necklace a different way. Or maybe your daughter will want to wear it to her prom someday….
