Buying Guide: Key Purchase Considerations
What size is right for your project? Larger stones (2-4 inches) create bold focal points and require fewer pieces for coverage, while smaller pebbles (1/4″ – 3/4″ or 2-3 inches) work well for container plants and edging. For pathways, consider a mix of mid-sized rocks for stable footings.
Which finish suits your space? Polished stones provide a sleek, modern look and are less dusty; natural stones offer a rugged, organic vibe that blends with garden textures. Color depth matters: deeper black hues can read more dramatic in shaded areas, while lighter blacks show highlights in sun.
Where will the rocks be used? Outdoor landscapes benefit from stones that resist fading and have good erosion control. Indoor uses—planters and vases—prefer lighter handling and a clean, dust-free surface. Aquariums and water features require non-toxic materials and stable color when submerged.
Durability and maintenance: natural river rocks are long-lasting and require minimal upkeep. Some stones may have surface cracks or small imperfections; these do not affect performance but affect aesthetic uniformity. Consider sealing options if you want extra gloss or moisture retention.

Care and maintenance tips
- Rinse new stones to remove dust before placing in planters or aquariums.
