bort (BAWRT) - n., imperfectly crystallized or low-quality diamond in granular aggregate or small fragments, used as an abrasive or industrial curring.
Also spelled boart or boort or bortz. Adopted in 1622 probably from Dutch boort, tiny waste diamond pieces produced in the gem cutting process, behind which is a further chain of speculation: "probably from Old French bourt, bastard, from Late Latin burdus, hinny, probably of Celtic origin," says the Random House Dictionary.
