Appearance
Coldstream is a multi-coloured quarried stone with striking natural variation. Shades of blue, purple, grey, brown, and gold run throughout the rock, creating a warm, earthy palette that integrates seamlessly into both modern and native landscapes. No two pieces are identical, giving every project its own unique character.
Common Uses
Coldstream is one of the most versatile materials in landscaping:
- Driveways & pathways – crushed grades compact well while maintaining a decorative surface.
- Retaining & dry-stone walls – angular blocks interlock naturally and weather attractively.
- Feature boulders – bold statement pieces for gardens, entryways, and parks.
- Gabion stone – stable and angular, ideal for basket and structural applications.
- Garden beds & edging – adds texture, depth, and colour variation to plantings.</li>
- Water features & creek beds – tones and textures pair naturally with water and vegetation.
Workability
Coldstream is a hard, durable stone, making it reliable for long-term use.
- Cutting & drilling – achievable with specialist equipment, especially for water features.
- Shaping – less suited to precise carving; generally used in its natural angular form.
- Placement – angular faces allow secure stacking in retaining walls and gabions.
Unique Qualities
- Distinctive multi-colour variation – creates depth and individuality in every installation.
- Flexible across scales – available from compacted fines to large-format feature boulders.
- Durable volcanic composition – built to withstand both structural and decorative applications.
- Seamless integration – earthy tones complement timber, steel, and native planting schemes.
