Onyx Black Cobbles from Kelkay are a decorative aggregate that consist of 40-60mm dark grey or black mixed shaped cobbles. Suitable for a wide range of landscaping projects. Onyx Black Cobbles are suitable for use in ponds and water features as they are fish friendly in their natural state. 

Onyx Black Cobbles are ideal for:

• Borders and Rock Gardens
• Pebble Pools and Fountains
• Gabions 
• Ponds and Stream Beds

Our aggregate range is delivered in 1 cubic metre bulk bags on a non returnable pallet. The Bulk Bag holds around 800-850kg of stone, enough to cover 10 square metres.

Please note: Images show aggregate when wet. 

Delivery

The Kelkay aggregates are delivered on a non returnable pallet. The pallet is unloaded from the delivery vehicle using a tail lift and a hand pump truck which requires a flat, firm surface for unloading. In some cases, this may mean kerbside delivery only. Please make us aware of any vehicle access restrictions such as height, width or weight limits as failed deliveries due to access issues may incur a failed delivery charge.
