Our Mixed Glacial boulders are one of the most stunning natural materials available. Their colours can range from from light to mid-grey, pinks and buffs. Our celtic boulders are often darker in colour, sometimes they can be a rich green which is enhanced when wet. Most of these boulders are well rounded although some can vary and can be more angular in shape. Sizes can range from a football size to anything up to the the size of a small car. Most common sizes range from 500-1500mm. Call us directly to discuss your size, shape and quantity requirements.
