Mixed New Zealand Lava Rock Boulders 4kg

4Kg of Mixed Sizes Grey Round New Zealand Lava Rock Boulders 

These Natural Lava Rocks are unique, very attractive, and come from New Zealand.  These lovely, oval-rounded boulders of grey lava rock vary in size from an Emu egg to a duck egg to an eyeball. They are speckled grey in colour and have an even-textured surface. 

The satisfying rock shapes are ideal as a feature or clustered together to create a natural, river-rock aquascape.

Sizes vary as they are a natural tumbled product.
