The Blue/Black Limestone gravel is known locally as Hardstone. Formed by the accumulation or deposition of mineral or organic particles, this type of gravel falls under the Sedimentary Rock category.

This Blue/Black Limestone is graded with the largest stone no bigger than 20mm. Due to the screening process, this can mean that smaller sizes of 10mm can be found within this product.

The colours may vary slightly between batches. If this colour isn’t suitable, our Pink Limestone is an attractive alternative to standard coloured gravel and will add a shine to any garden.

After bagging, the Limestone gravel chippings can often take on a dusty appearance, making the stone appear a different colour. Once your project is complete, wash away the dust and allow the true colour of the stone to emerge.

We pride ourselves in customer service and offer the following choices when you purchase your Blue/Black Limestone Gravel Chippings:

  • Free sample bags, filled to a weight of 1kg
