Description
Arthur Blue Quartzite from Brazil is a luxurious and highly durable natural stone characterized by a deep blue, bluish-gray, and green-toned background enriched with flowing white and occasional golden veining that creates an exotic, wave-like movement across the surface. Its pattern typically shows medium to high variation with dramatic linear and cloudy structures, giving each slab a unique, artistic appearance suitable for premium architectural projects.
Texture & Structure:Medium- to fine-grained crystalline structure with interlocking quartz crystals, providing very high density, compactness, and low porosity. The stone is extremely hard and resistant to abrasion and weathering due to its metamorphic quartzite formation.
Hardness & Physical Properties:
- Mohs hardness: ~7
- Compressive strength: 180–200 MPa
- Flexural strength: 14–16 MPa
- Water absorption: 0.1–0.3% by weight
- Density: 2.64–2.70 g/cm³
Chemical Composition (% by weight):
- SiO₂ (Quartz): 92–97%
- Feldspar: 1–4%
- Mica & accessory minerals (biotite, muscovite): 1–3%
- Trace iron oxides (responsible for golden/green tones): <1%
Mineral Composition: Predominantly quartz recrystallization with minor feldspar inclusions, biotite streaks, and iron-bearing minerals contributing to color variation and veining effects.
Usage: Ideal for luxury interior and exterior applications such as kitchen countertops, island tops, bathroom vanities, feature walls, flooring, staircases, reception areas, façades, and high-end commercial or hospitality projects.
Surface Finish Options: Polished, honed, leathered, brushed, and flamed finishes are commonly available, each enhancing different aspects of the stone’s color depth and texture.
Maintenance: Low maintenance due to high quartz content. Recommended sealing upon installation and periodic resealing depending on usage. Clean with pH-neutral stone cleaners; avoid acidic or abrasive chemicals to preserve surface integrity and polish.
