Nice quality Dumortierite tumblestones, measuring 20-30MM approximately.
These are a nice banded blue colour, which is reasonably pale compared to some Dumortierite.
These stones would make a nice decorative stone gravel for a fishtank or an aquarium, and look great in a vase, flowerpot, etc. Because of their colour, they contrast nicely against black stones and other shades of blue, too.
