Bort
From Wikipedia, the free encyclopedia
For other uses, see Bort (disambiguation).
Bort or boart is a term used in the diamond industry to refer to shards of gem-grade/quality diamonds. In the manufacturing and heavy industries, "bort" is used to describe dark, imperfectly formed/crystallized diamonds of varying levels of opacity. The lowest grade, "crushing bort", is crushed by steel mortars and used to make industrial-grade abrasive grits. Small bort crystals are used in drill bits. The Democratic Republic of the Congo provides 75% of the world supply of crushing bort.
Additional (V.Rare) meaning: A term of endearment: I.E. You are a bort or Hello you Bort.
