Most lavastones used in construction are grey to black in colour and while some exhibit a 'frothy' appearance due to the gases contained in volcanic eruptions, others are very dense with no visible holes.These stones are hard wearing, scratch and stain resistant making them extremely versatile, and suitable for a range of applications.
