Mint Sandstone is an ivory to light beige quartz-rich sandstone with subtle golden undertones, quarried in Gwalior, Madhya Pradesh, India. This durable natural stone is prized for its hard, fine-grained texture, making it suitable for a wide range of architectural and landscaping applications. Although in the stone trade it is sometimes referred to as marble due to its ability to take a smooth finish, geologically it is classified as a sandstone (quartz arenite), not limestone or marble.
Texture & Pattern
Grain: Fine to medium-grained quartz crystals, tightly bonded.
Coloration: Ivory-light beige base, often with subtle golden, yellowish, or light brown shades.
Pattern: Consistent, uniform appearance with minimal veining, sometimes showing fossil imprints or ripple marks typical of sedimentary stones.

Applications & Usage
- Exterior & interior wall cladding
- Paving, pathways, and landscaping
- Flooring (residential and commercial)
- Pool surrounds & garden features
- Stairs, risers, coping stones
- Countertops and tabletops (with proper sealing)
- Monuments and decorative artifacts
Maintenance
Requires sealing for stain resistance, especially in wet or high-traffic areas. Clean with mild soap and water; avoid acidic cleaners. Periodic re-sealing (every 1–2 years) recommended to maintain surface finish and durability.
Available Cutting Sizes (cm)
