River Gravel (20mm)Our 20mm River Gravel is a naturally rounded decorative stone featuring a rich blend of cream, coffee, brown, and grey tones. Slightly larger than finer river stones, this river gravel is ideal for landscaping projects where both appearance and stability are important. Its smooth, semi rounded shape creates a natural look that works beautifully in garden beds, pathways, driveways, and between pavers. Commonly used in river rock landscaping across
