A kind of semi‐precious stone with an intense blue colour sometimes flecked with gold. The main source used in the ancient world was in the mountains of Badakhshan, northern Afghanistan, from where it was traded extremely widely, especially to Egypt. Lapis lazuli was used as inlay in the manufacture of ornaments, jewellery, seals, etc. Tepe Hissar and Shahr‐i Sokhta seem to have functioned as trading centres for the working and distribution of lapis lazuli.
