Description
Aurora Rainbow Quartzite is an exotic Brazilian quartzite defined by a soft creamy beige to ivory background enriched with striking fluid veining in blue to lavender hues, complemented by subtle brown and pinkish-brown accent streaks. The veining pattern is highly organic yet visually balanced, often appearing symmetrical or harmoniously flowing across the slab due to the natural deposition and possible selection cutting of the blocks. This creates a distinctive “aurora-like” visual effect, where cool and warm tones intertwine in elegant motion, making each slab highly decorative and unique.
Texture & Pattern: Medium to fine crystalline quartzite texture with a compact, interlocking grain structure; surface shows a smooth, glassy crystalline reflection when polished. The pattern is directional and wave-like, with continuous flowing veins and soft cloudy transitions between color zones.
Mineralogical Composition (% by weight):
- Quartz (SiO₂): 85–95%
- Feldspar: 2–6%
- Mica and trace minerals (including iron oxides responsible for color variation): 1–5%
Chemical Composition (% by weight):
- SiO₂: 85–95%
- Al₂O₃: 1–4%
- Fe₂O₃: 0.5–2% (contributing to brown/pink tones)
- Other oxides (K₂O, Na₂O, CaO traces): <2%
Physical & Technical Properties:
- Apparent Density: 2.65 – 2.70 g/cm³
- Water Absorption: 0.1 – 0.3%
- Compressive Strength: 140 – 160 MPa
- Flexural Strength: 12 – 16 MPa
- Mohs Hardness: 7
- Abrasion Resistance: High
Surface Finish Options: Polished (high gloss, enhances veining contrast), honed (matte, softer appearance), leathered (textured, natural feel), brushed, and occasionally flamed for exterior use.
Applications: Luxury countertops, kitchen islands, bathroom vanities, feature walls, flooring, reception desks, hotel lobbies, staircases, and high-end residential or commercial interiors.
Maintenance: Requires periodic sealing to enhance stain resistance despite low porosity; clean with pH-neutral stone cleaners; avoid strong acids and abrasive chemicals to preserve polish and color integrity.
