Aquamarine and Amethyst still have character in low-end mineral form though - particularly Amethyst when it has white matrix mixed in with it to form 'Dog Tooth / Chevron Amethyst - plus they are birthstones, so they'll always attract attention.
Carnelian has patterns of red/orange veins - so that's not exactly dull either. Chrysoprase also has characters.
Branca Onyx though is just a plain white translucent stone with little going for it visually.
