Black Basalt Gravel 20mm
This hardwearing angular volcanic stone, also known as Black Granite, is becoming increasingly popular due to its contemporary shade of charcoal grey that darkens to black once wet. Resistant to moss growth it will maintain its beautiful looks for years. It is perfect for drives and footpaths but as a fish friendly product it is also suitable for ornamental water features and fish ponds. The actual size is 14-20mm but as a naturally quarried product it may vary in shapes, colour and size - please see Sizing Information. We also stock Black Basalt in 6mm, 10mm & 14mm gravels.
