Naturally deposited Pebbles and Cobbles on Cawsand Bay Beech, Cornwall. The best range of different materials I’ve ever seen. Sadly, pebbles of this quality are very rare and I have never seen any for sale in the UK.
Using Pebbles / Cobbles in your garden
By far the most common type of pebbles and cobbles available to the landscape trade are Scottish Cobbles, which have been distributed across the whole of the UK for many decades. The Scottish cobbles supplied by Natural Stone and Timber are quarried from a site deep within the forests of Morayshire. These ancient forests grow on land that once formed the pre-historic coast of northern Scotland. These beautiful stones have been fashioned over millions of years by the tireless motion of the Moray Firth and River Spey.

Each cobble is unique, displaying its character through pleasing variations in colour, shape and texture. In a spectrum from sparkling white to jade black, encompassing perfectly smooth spheres through to textured ovoids.
Scottish pebbles and cobbles are a versatile product and can be used on numerous landscaping applications, such as:
- Small ornamental streams
