Description
Kota Black Sandstone (also traded as K. Black) тАФ a deep, dark stone sourced from the Kota region of Rajasthan тАФ is the boldest member of Stone HarborтАЩs sandstone range. Its near-black to dark charcoal colouration creates a dramatic visual statement that has made dark Indian sandstones increasingly sought-after in contemporary architecture and premium residential design. In a product category dominated by warm terracotta and neutral grey tones, Kota Black stands apart.
The stone is quarried in Rajasthan, processed to export standards, and exported by Stone Harbor to clients across Europe, the Middle East, and Asia. It is particularly effective as a contrast element тАФ paired with lighter stones or pale interiors for maximum visual impact, or used in monochrome installations where depth and texture are the design intent.
Origin and Composition
Kota Black Sandstone is a sedimentary stone from the Kota region of Rajasthan, India. Its dark colouration comes from high concentrations of dark minerals and oxidised organic matter within the quartz-dominant matrix. The stone has a fine grain structure and good compressive strength, making it suitable for both decorative and structural applications.
