Rainbow Stone is a decorative landscaping gravel known for its vibrant, multi-coloured appearance. It’s popular in Perth, Western Australia, for both aesthetic and practical uses in residential and commercial outdoor spaces.
 
What is Rainbow Stone Made From?
Rainbow Stone is a naturally tumbled river stone sourced mainly from riverbeds or quarries.
It consists of a mix of stones in colours like red, pink, gold, cream, white, and grey.
The stones are usually smooth and rounded, ranging in size from 10mm to 20mm (sometimes larger).
 
What is Rainbow Stone Ideal For (Especially in Perth, WA)?
Rainbow Stone is ideal for:
Garden beds & planter surrounds – adds colour and contrast to plants
Pathways & courtyards – attractive and easy to walk on
Driveways & verge areas – durable and doesn’t get as dusty as finer gravels
Drainage areas – allows water to pass through easily
Decorative ground cover – low maintenance alternative to mulch
Pool surrounds – doesn’t retain heat as much as darker stones
 
Perth Considerations:
Well-suited to Perth’s dry climate, as it doesn’t degrade like organic mulch
Complements modern and native garden styles common in WA
 
Recommended Thickness for Rainbow Stone Layers
General landscaping (decorative cover):
🔹 4–6 cm (40–60mm) deep
Paths or driveways (with light traffic):
🔹 7–10 cm (70–100mm) over a compacted base
Weed suppression:
🔹 Combine with weed mat underneath for best results
 
How to Maintain Rainbow Stone Surfaces
Rake occasionally to redistribute stones and remove debris.
Top up every 2–4 years as some stones may sink or get displaced.
Blow or sweep off leaves and dirt to keep the surface clean.
Install proper edging to contain the stones and prevent spreading into unwanted areas.
Weed control – use geotextile fabric beneath to reduce weeds, and spot treat any that break through.
