Oltu Stone, also referred to as Black Amber, is a remarkable Geographically Indicated Product originating from the Oltu district in the Erzurum province of Turkey. This unique stone is a type of lignite, formed from organic matter, and is renowned for its deep black color, smooth surface, and shiny appearance. Oltu Stone has been cherished for centuries, both for its aesthetic qualities and its cultural significance.

The geological formation of Oltu Stone consists of sedimentary deposits found in Neogene layers, typically within mangrove-like strata.

Craftsmen meticulously select the stones based on size and quality, taking into account any natural inclusions or cracks.

The crafting process involves breaking the stones into smaller pieces using specialized tools, followed by shaping them into the desired forms. This requires a high level of skill and precision, as artisans aim to minimize waste during the cutting process.
