At HRCSTONE, we specialize in selecting the finest blocks to ensure color consistency and structural integrity. Whether you are looking for a polished mirror finish for a grand hotel lobby or a subtle honed surface for a modern residential bathroom, Black Marquina Marble delivers an unmatched level of sophistication. This guide provides a comprehensive technical and aesthetic overview of why this Chinese black marble remains a global bestseller.

Stone Information: Origin and Technical Excellence

The geological formation of Black Marquina Marble is as fascinating as its appearance. It is a recrystallized limestone characterized by its fine grain and rich bituminous content, which provides its signature deep black hue.

1. Geological Origin: Primarily Guangxi Province, China (The Guangxi Black variety is known for its purity) and Hubei Province.

2. Color Profile: A solid black base with irregular white calcite veins that vary from thin, hairline strokes to thick, bold streaks.

3. Mineral Composition: High calcium carbonate content with natural carbonaceous inclusions.

4. Density: Approximately 2.68 - 2.72 g/cm3, providing a sturdy foundation for heavy-duty applications.

5. Water Absorption: Extremely low (0.15% - 0.20%), ensuring excellent resistance to moisture when properly treated.

6. Hardness: Rated at 3-4 on the Mohs scale, offering the perfect balance for intricate CNC carving and durable flooring.

Available Slab Size(s): Precision and Variety

To cater to large-scale commercial facades and custom furniture pieces, HRCSTONE provides a wide range of slab dimensions:

1. Large Gang-saw Slabs: Typically 2400mm x 1200mm and up, with jumbo sizes reaching 2800mm x 1600mm. These are ideal for book-matched wall installations where the veins flow seamlessly across panels.

2. Half Slabs (Strip Slabs): Ranging from 600mm to 900mm in width with random lengths. These are cost-effective options for stairs, window sills, and smaller vanity tops.

3. Thickness Standards:

• 18mm (3/4"): The global standard for interior flooring and wall cladding.

• 20mm (3/4"): Preferred for high-end kitchen islands and countertops.

• 30mm (1 1/4"): Specialized thickness for architectural carvings, thick-edge tables, and heavy-duty thresholds.

Available Tile Size(s): Standard and Bespoke Formats

Our tiles undergo rigorous calibration to ensure perfectly flat surfaces and 90-degree corners for easy installation:

• Standard Square Tiles: 305 x 305mm (12"x12"), 457 x 457mm (18"x18"), and 610 x 610mm (24"x24").

• Rectangular Formats: 300 x 600mm (12"x24") and 600 x 1200mm (24"x48").

• French Pattern & Mosaics: We also offer Nero Marquina in hexagon, herringbone, and basketweave mosaics for feature walls and shower floors.

• Custom Cuts: We provide Cut-to-Size services based on your project shop drawings to minimize on-site waste.

Available Surface Finishes: Crafting the Aesthetic

The finish of Black Marquina Marble dramatically alters its personality and use case:

• Polished: The Signature look. It maximizes the black depth and makes the white veins pop. This finish reflects light beautifully, adding a sense of spaciousness to interiors.

• Honed: A smooth, satin-like matte finish. It is increasingly popular in modern minimalist designs as it reduces glare and hides daily wear and tear more effectively.

• Leathered (Brushed): A textured finish that follows the natural stone grain. It provides an organic feel and is excellent for anti-slip requirements or tactile wall features.

• Acid-Washed: Creates a weathered, antique appearance that highlights the white calcite veins in relief.
