The quarry website places Shayan in Bavanat, Fars province. It is a source of Iranian cream marble. This guide retains the producer’s stated location, distinguishing it from the Dehbid name often used in trade.
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.
