The density or specific gravity of amber is about 1.05 - 1.10 g/cc. Polystyrene (without any dense additives) runs 0.96 - 1.05 so it may not be possible to distinguish amber from polystyrene by floating in salt water. Some additional tests may be needed if the beads float and don't look like, or smell like, amber.
