Gem stockpiles under workshops are storing some cut cabochons made from granite. One of them was used in Jeweler's workshop to encrust furniture: mica mechanisms of superior quality. Onul Morulunal, siege engineer/mechanic/jeweler, is just going to take this item he crafted few minutes ago from this workshop down to storages.

Save and world generated in 40.20, save moved to 40.21. No other fortresses or adventurers retired in this world.
