Description
Verde Borgogna Quartzite is an exotic natural stone quarried in Birjand, Khorasan Province, Iran, known for its dramatic deep forest-green to dark-green background. The stone is characterized by contrasting white, brown and reddish mineral veining, creating a highly expressive and directional pattern.
Despite being commercially marketed as a quartzite, Verde Borgogna may be petrographically classified in some sources as a serpentinite or silicate-rich metamorphic stone rather than a true quartz-dominant quartzite. Therefore, mineralogical classification and technical properties can vary between quarry selections and should be confirmed through laboratory testing for a specific block.
Texture & Pattern
- Color:Deep forest green, dark green
- Veining: White, brown and reddish tones
- Pattern: Irregular, sweeping and directional
- Texture: Fine to medium-grained, dense and compact
- Movement: Medium to high
- Finish: Can achieve a deep, attractive polish
Indicative Technical Properties
- Density: 2,680–2,830 kg/m³
- Water Absorption: 0.25–0.55 %
- Flexural Strength: 15–20 MPa
- Compressive Strength: 150–170 MPa
- Hardness: Approx. 4–7 Mohs
Values are indicative; actual properties vary by quarry selection and should be confirmed by laboratory testing.
Chemical & Mineral Composition
Indicative chemical composition: SiO₂ 35–55%, MgO 20–40%, Fe oxides 3–10%, CaO 0.5–8%, Al₂O₃ 0.5–5%, with trace Cr₂O₃ and other oxides.
Possible minerals: serpentine, quartz, talc, chlorite, carbonate minerals, magnetite and other silicates.
Applications
Suitable for:
- Luxury countertops and vanities
- Feature walls and cladding
- Flooring
- Fireplace surrounds
- Bars and reception desks
- Hotel and residential interiors
- Tables and custom furniture
- Bookmatched decorative panels
- Selected exterior applications subject to testing
Maintenance
- Use a suitable stone sealer and pH-neutral cleaners.
- Avoid vinegar, lemon, acidic cleaners, abrasive powders and aggressive chemicals.
- For countertops, test stain and chemical resistance and seal regularly.
Note: Because Verde Borgogna can contain softer serpentine or carbonate-rich minerals, its hardness, acid resistance and durability may differ from conventional quartzite.
