REZA MOLAI SELECTION

Guide to Iranian materials

Onyx: areas of origin, materials and further reading.

From area to block: reading a selection

Eight localities identified by Reza Molai for exploring Iranian onyx.

An area can include several quarries and selections. A material enquiry should record locality, quarry and block number. Qorveh and Bijar, like Sirjan and Kerman, remain separate entries in this guide.

For comparison, request views of the block faces, usable dimensions and photographs of a cut sample. Record sample thickness, finish and cutting direction. Photographs should identify the batch.

Area profiles do not declare immediate availability. Quantities, dimensions and lead times are confirmed for the actual material offered.
