Oriental Black Marble, also known as China Marquina Black Marble, is an exquisite natural stone quarried in China. As the name suggests, this marble is predominantly black, creating a bold and luxurious backdrop for any interior design.

The primary color of Oriental Black Marble is a deep and rich black, providing a sophisticated and elegant look. Scattered throughout the black background are prominent white quartz veins, which create a striking and dramatic contrast. The white veins meander gracefully across the surface, resembling flowing rivers or elegant tree branches, adding a touch of movement and artistic flair to the stone.

The combination of black and white elements in Oriental Black Marble makes it a favored choice for various interior applications. It is commonly used for wall cladding, flooring, kitchen countertops, bathroom vanities, and other decorative accents. The marble's dramatic appearance can bring a sense of luxury and grandeur to any space, making it suitable for both contemporary and traditional designs.

Due to the natural variation of marble, each slab of Oriental Black Marble is unique, so it's essential to view and select specific slabs for a project to ensure they align with the desired design.

To maintain the beauty and integrity of Oriental Black Marble, proper sealing and regular maintenance are recommended. This will help protect the stone from potential staining and ensure it continues to showcase its exquisite aesthetics for years to come.
