I’m sourcing dark natural stone wall cladding for a high-end villa interior in Riyadh, to cover both sides of a concrete wall with a total area of 32–36 m². The required stone types include black basalt, dark granite, volcanic stone or dark slate, with rough and matte non-polished finishes such as natural split-face, bush-hammered or flamed, matching the effect shown in the attached photo. Preferred panel size is large format around 1200×600mm, with thickness of 20–25mm. 

Please quote your best price, thank you.
