emery
Dark corundum variety
Emery is a dark granular rock used as an abrasive for grinding and polishing.
Ground into powder or bonite to boards, cloth, or paper, it smooths and sharpens: an emery board for filing nails, emery cloth for metalwork.
The rock consists mainly of corundum mixed with iron oxides.
