Rosso Siena Granite is a striking, medium to coarse-grained natural stone quarried in South Africa, celebrated for its deep, warm coloration and high durability. Its rich tones and crystalline depth make it an ideal choice for both interior and exterior applications in luxury and high-traffic environments.

Color & Aesthetic Characteristics

• Primary Color: Deep burgundy-red to wine red
• Accents: Features black, gray, and white speckles or crystals
• Pattern: Intricate and variable, with irregular mineral swirls or crystalline patches
• Visual Effect: Luxurious and dramatic, suitable for bold, high-impact design statements
• Texture & Structure Grain: Medium to coarse-grained, with a clearly visible crystalline structure
• Finish Sensitivity: The depth of color and texture is particularly enhanced in polished finishes, while leathered or brushed finishes bring out the natural contours and mineral variation.

Physical and Mechanical Properties

• Water Absorption : 0.20% (by weight)
• Density : 2,620 kg/m³
• Flexural Strength : 15.0 MPa
• Compressive Strength : 206.2 MPa
• Porosity : Low (excellent compactness)
• Hardness (Mohs scale) : ~6–7
• Slip Resistance : High in flamed/brushed finishes; moderate in polished

Chemical and Mineral Composition (% by weight)

• Quartz: ~28–32%
• Feldspar (Plagioclase & K-feldspar): ~55–60%
• Mica (Biotite): ~5–8%
• Iron Oxides & Accessory Minerals: ~2–5% (contributing to red hues)

Available Surface Finishes (2 cm & 3 cm thickness)

• Polished – Glossy, highlights deep color and crystalline richness
• Honed – Smooth, matte for a more contemporary appearance
