The supplier’s listing identifies Shah Maleki Harsin and locates the quarry in Harsin, Kermanshah province. This is a producer’s commercial source; the Harsin name does not automatically identify every light block from the region.
An offer is easier to read when three levels are distinguished: area of origin, quarry name and trade name. Chahmorghi is documented in Dehbid district; Shayan’s official website identifies Bavanat. Both are in Fars.
Breccia contains angular fragments held in a matrix or cement. The USGS example at Titus Canyon shows limestone pieces cemented by calcite: it explains the structure, not an Iranian quarry.
This guide brings together different appearances: Chahmorghi and Shayan cream stone, Persian Silk greys and Scatto & Bianco crystalline white. These names guide research; the quarry profiles document the producer’s stated origin.
