These are lovely Bloodstone tumblestones, a decent grade of the stone. Typically they are a browny green stone with red spots – ‘blood drops’ on the surface of the stone, as it were.
These stones are a good contrasting stone against lighter things – they make nice gravel for tanks, aquariums, terrariums, etc.
Available in a few sizes, from 10-15MM all the way up to larger 30-40MM stones.
We sell other Bloodstone products, including larger tumblestones – for more information about the stone, and a list of our other products, visit our Bloodstone page.
We don’t just sell Bloodstone, either, we have a range of hundreds of different tumblestones.
