We can’t talk about bling without mentioning diamonds. Of course, we have to bring this precious stone to your nail jewelry manicure. Diamonds, along with their cousins, ruby, jade, sapphire, opal, and everyone else in the family tree, are the definition of bling. Just one of these gems on your nails makes you certified flashy. You can mix and match rhombus-shaped stones with triangle or circle ones to add dimension. Or opt for gem-crusted decals like a snake or planet to carry your personality through to your digits.
