Rosa Duquesa Marble is a distinctive natural stone quarried in Urdax, Navarra, in the North of Spain, celebrated for its rich terracotta to brick-red base color, beautifully contrasted with lighter hues, creamy white streaks, and fine veining patterns. This marble brings a warm, rustic elegance that is ideal for both classic and contemporary spaces.

Appearance (Texture & Pattern)

Color Base: Deep terracotta brick red.

Veining: Soft to pronounced white streaks and light beige to pinkish hues.

Pattern: Irregular but elegant veining that flows in gentle waves or linear streaks, creating visual movement and depth.

Texture: Typically fine-grained, compact structure with a uniform crystalline texture, giving it a smooth surface when polished.

Technical Properties

• Water Absorption : 0.30%
• Density : 2660 kg/m³
• Flexural Strength : 21.4 MPa
• Compressive Strength : 99.0 MPa
• Mohs Hardness : ~3 to 4 (moderately soft)

Chemical Composition (% by weight)

Typical of carbonate marbles:

• CaCO₃ (Calcium Carbonate): 95–98%
• MgCO₃ (Magnesium Carbonate): 1–2%
• SiO₂ (Silicon Dioxide): ≤1%
• Fe₂O₃ (Iron Oxide): Trace amounts, responsible for red tone
• Al₂O₃ (Aluminum Oxide): Trace
• Organic pigments/oxides: Trace, contribute to the unique coloration

Mineralogical Composition

• Calcite: ~90–95%
• Dolomite: ~1–3%
• Quartz: ≤1%
• Iron oxide and hematite inclusions: Provide the reddish coloration

Applications

Rosa Duquesa Marble is well-suited for:

• Interior flooring & wall cladding
• Bathroom vanities & shower walls
• Kitchen countertops (less common due to lower hardness)
• Staircases, window sills, fireplace surrounds
• Columns and balustrades
• Interior décor elements, furniture inlays
• Its warm tone makes it ideal for luxurious interiors such as hotels, classical residences, and restoration of historic buildings.

Maintenance

Seal regularly to prevent staining and etching (especially in wet areas). Clean with pH-neutral stone cleaners. Avoid acidic or abrasive cleaners (e.g., vinegar, lemon juice). Polish periodically to maintain luster in high-traffic areas.
