Two things unearthed that are of considerable interest

Archaeology and mining yield some interesting finds.

First, the mining.

Exceptional 500-carat diamond found in South Africa's Cullinan mine

(In case you're not up on your gemology, the Cullinan was the largest diamond ever found until the Golden Jubilee, and it spawned the two largest blue-white diamonds in the world, the Cullinan I and Cullinan II, in the British crown jewels (crown and scepter, respectively).

Now the archaeology.

Emperor Nero's rotating banquet room found

Of course, that's the PG-rated news.

This one's a little more racy.

Pity the Emperor never got to "party" in his rotating room.
