The geological properties of a rock will not only affect how it performs in various applications, but also how it looks when used as a decorative pebble. Quartz or quartzite can be a wide range of colours; river pebbles tend to be brown, blue and sometimes white; and basalt appears blue to black. This all depends on nature and how the rock came to be – part of a river bed, formed in a volcanic process, or sedimentation.
Metromix sell various sizes of decorative pebbles which are used in exposed concrete paths and driveways, in polished concrete, and as free draining pebbles in landscape gardens.
Note: Due to the natural source of our decorative pebble range, there will be natural variations in the colour and shape of pebbles.
