These are handpicked rounded welsh quartz boulders in varying sizes from 300 to 600mm (approx). They are heavy, very versatile and tend to be best used as features in a pond, waterfall, rockery or as stand alone pieces on gravel or slate mulching areas. Stones are natural mixed colours generally grey pink and brown. They tend to be elongated and smooth, looking great when wet or when planted around for a natural rugged landscape appearance.
