1. Poorly crystallized diamonds used for industrial cutting and abrasion.
2. A carbonado. (American Heritage)
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. (Wikipedia)

Perhaps one of our freshly minted Wordie Icelandic experts might be able to enlighten us further?

Was Ernest at Doubleday’s sport.

Though grew less adroit
And Ernest’s career was a bort.
