I have no idea what type of stones they use, but I'm sure they use the same method of attaching them to the dial as the lumed hour indices. If you're concerned about them falling off and rolling around like a pinball, don't be. They're solid. If you're asking about what they use instead of actual diamonds, I have absolutely no idea.
