Culli Gold Marble

Culli Gold Marble is an exotic natural marble quarried in Morocco, distinguished by a deep dark grey-green to charcoal background with subtle brownish undertones. Its dramatic dark base is crossed by an intricate network of golden-brown, amber and rust-colored veins, creating a luxurious, organic appearance reminiscent of fossilized structures, roots or natural mineral formations.

Texture

• Fine- to medium-grained crystalline texture
• Compact natural stone structure
• Smooth, dense surface
• Natural mineral variation throughout the slab
• Capable of achieving a high-gloss polished finish

Veining & Pattern

The defining feature of Culli Gold Marble is its complex web-like veining. Golden-brown, amber and rust-colored veins range from extremely fine lines to wider fractured strokes and spread irregularly across the surface. The strong contrast between the dark charcoal background and warm metallic-looking veins produces a dramatic and luxurious appearance. Vein density and direction can vary significantly between blocks and slabs.

Typical Technical Properties

Representative ranges for comparable Moroccan dark marble; actual quarry test results may vary. 

• Apparent Density: 2,680–2,720 kg/m³
• Water Absorption: 0.30–0.60%
• Open Porosity: 0.3–1.2%
• Compressive Strength, Dry: 90–120 MPa
• Compressive Strength, Wet: 75–95 MPa
• Flexural Strength, Dry: 9–13 MPa
• Flexural Strength, Wet: 7–10 MPa
• Mohs Hardness: 3–4

Chemical Composition - Component Approx. % by Weight

• CaCO₃: 75–90%
• MgCO₃: 3–12%
• SiO₂: 2–7%
• Fe₂O₃ + FeO: 0.5–4%
• Al₂O₃: 0.2–2%
• MgO: 1–4%
• Other oxides: <2%
• Loss on Ignition: 40–44%

Mineral Composition

• Calcite: 70–85%
• Dolomite: 5–15%
• Quartz: 2–7%
• Clay / Phyllosilicate Minerals: 1–5%
• Iron-bearing Minerals: 1–4%
• Other Accessory Minerals: <2%

The golden, amber and rust coloration is primarily associated with iron-bearing mineral phases, while the dark grey-green coloration can result from minor silicate, carbonaceous and other accessory minerals.

Recommended Uses

Culli Gold Marble is particularly suitable for premium interior applications:

Feature walls, Interior wall cladding, Luxury flooring, Bathroom walls, Vanity tops, Countertops, Fireplace surrounds, Hotel and hospitality interiors, Reception desks, Decorative panels, Tabletops and furniture, Columns and architectural features, Sculptural and artistic applications, etc.

For heavily trafficked flooring or exterior applications, project-specific testing is recommended.

Maintenance

Culli Gold Marble is a calcareous natural stone and requires appropriate care.

• Clean with a pH-neutral stone cleaner.
• Avoid vinegar, lemon, acidic detergents and descaling chemicals.
• Wipe spills promptly to minimize staining.
• Use a suitable penetrating sealer where appropriate.
• Reseal periodically depending on the application and level of use.
• Avoid abrasive powders and harsh cleaning pads.
• Use cutting boards and protective mats on countertops.
• Natural fissures and filled veins should be professionally evaluated before installation.

Note: The chemical, mineralogical and mechanical values above are representative ranges for comparable Moroccan marble and should be replaced with quarry-specific laboratory test results when used for formal architectural or engineering specifications.
