About Union Cartel Natural Stones

Established in 2019 under the leadership of CEO Sharadchandra Manganawar, Union Cartel was born from a vision to bring India’s most monumental natural stones to the global stage. Sourcing exclusively from the premium quarries of Karnataka, we combine ethical extraction with rigorous supply chain management to deliver granite and marble that defines contemporary architectural elegance.

QUALITY & SOURCING

Our stone is selected at the quarry, where blocks are assessed for colour consistency, grain, and structural soundness before they are cut. Working directly with quarry operators in India which gives us oversight of material at each stage like selection, cutting, finishing, and inspection, so that what reaches the buyer matches what was agreed.

​

We hold sourcing to practical standards: material is checked for cracks, fissures, and colour variation, and finishes are inspected before crating. Where a project calls for specific dimensions, thicknesses, or surface treatments (polished, honed, flamed, or brushed), we confirm these against the order before dispatch. Our aim is straightforward to supply stone that is accurately represented, properly finished, and delivered in the condition the buyer expects.
