- Original Name:
- Angola Black
- Other Names:
- African Black，Nero Angola，Angola Absolute Black，Black Angola Granite
- Rock Character:
- Medium- to coarse-grained igneous rock with consistent, dense crystalline structure. Highly compact with minimal porosity, excellent mechanical strength, and uniform composition.

Description
Quarried in Angola, this prestigious natural stone is renowned for its intense, deep black color and uniform, fine to medium-grained texture. Its polished finish creates a sleek, sophisticated appearance that brings elegance to both modern and traditional designs.
Highly durable and resistant to scratches and heat, Angola Black is a practical choice for high-traffic areas. It is extensively used for kitchen countertops, bathroom vanities, flooring, and wall cladding. Its versatile, bold black provides a perfect backdrop for contrasting design elements.
As a natural stone, slight variations can occur, so viewing actual slabs is recommended. Angola Black Granite remains a top choice for those seeking a timeless, dramatic, and elegant statement piece.

FAQs
Yes—excellently suited. With very low water absorption (0.03–0.10%), high compressive strength (220–280 MPa), and excellent freeze-thaw resistance, Angola Black performs reliably in all climates. A flamed or bush-hammered finish is recommended for vertical exteriors to enhance grip and weather resilience.
Angola Black Granite, quarried in Angola, is a natural, untreated granite known for its true black color and long-term durability. In contrast, Indian Absolute Black is often not a true granite but a gabbro that is commonly treated with dyes or oils—and sometimes resined—to achieve its deep black appearance. Over time, these surface treatments on Absolute Black can degrade, yellow, or wear off, especially when exposed to UV light or harsh cleaners. Angola Black, being naturally dense and consistent without artificial enhancements, offers superior structural integrity, better weather resistance, and more reliable performance in both interior and exterior architectural applications. For projects prioritizing authenticity, sustainability, and lasting quality, Angola Black is generally the preferred choice.
Yes. Its extremely uniform pattern and minimal veining make it ideal for large slabs (up to 3.2m x 2.0m). When polished and installed by skilled fabricators, joints can be nearly invisible—perfect for seamless lobby walls, elevator surrounds, or minimalist countertops.
Sealing is optional but recommended for high-traffic interior floors (e.g., lobbies, retail). Due to its ultra-low porosity, it resists stains naturally, but an impregnating sealer adds protection against acidic spills (e.g., coffee, wine). Walls typically do not require sealing.
For patios, plazas, or pool decks:
Flamed: Creates a rough, non-slip texture (ideal for wet areas)
Bush-hammered: Uniform dimpled surface with high traction
Thermal + brushed: Combines safety with refined aesthetics
Avoid polished finishes outdoors—they become slippery when wet.
While granite is not typically used as a primary load-bearing material in modern construction, Angola Black’s high compressive strength (≥220 MPa) makes it suitable for:
Stair treads
Structural cladding panels
Monument bases
Countertop overhangs (with proper support)
Angola Black is one of the most consistent black granites globally. Minor variations may occur between quarries, but reputable suppliers batch-match slabs. For large projects, request pre-selection of slabs or lot certification to ensure visual uniformity.
Yes—with advanced CNC waterjet and bridge saw technology, Chinese and global fabricators routinely produce:
Curved reception desks
Radius countertops
Integrated drain boards
Custom monument lettering
Its homogeneous structure allows precise machining without chipping.
Common thicknesses:
Interior walls/cladding: 2 cm (¾")
Countertops: 2 cm or 3 cm (1¼")
Exterior cladding: 3 cm (1¼") or 4 cm (1½") for wind-load resistance
Paving tiles: 3 cm, 4 cm, or 5 cm
Custom thicknesses available upon request.
Yes. As a natural, non-toxic stone with:
No resins or dyes (in authentic grades)
Long service life (Above 100 years)
Recyclable at end-of-life
Low embodied energy vs. engineered materials
