All the posts for the water-gushing star are equally applicable here too!

I stumbled across the concept on wikipedia a couple of years ago and thought such a stellar remnant would make fantastic treasure world, hinted at in starport rumours, people killing to find it, and keep it hidden ....

Wiki articles are cooler than random silent Youtube movies with overlaid warbling noises.

Also, check out a similar "Diamond" Planet:

(Oh, and it appears that it's also being eaten by its star, just in case you needed more room for hilarious concepts science seems to imply/prove).

Diamonds are probably not forever. Already we can produce artificial diamond in small quantities. With the advent of nanotech, I figure diamond will be just another construction material manufactured from processed carbon, and no more valuable than aluminium. Heavy metals, OTOH, may still hold their value.
I figure by the Traveller era, nobody will be interested in a planet sized diamond.
Just my 2Cr.

Possibly.

Just an FYI, we've been making diamonds since the 70s, via super high pressure applied to carbon samples.

Hidden in the mountains
Under the earth and stone
A cubic mile of perfection
Treasure no one has known
.....
It's the diamond as big as the Ritz
What you gonna do with this
Tell me who's goin' to save you
When you're a slave to the
Diamond as big as the Ritz

Hey, this could be better than those "name a star after someone" scams..."buy your sweetie a several million carat diamond!"

Artificial diamonds since 1955:

I recall a story about a researcher, at Ames Research Center IIRC, who made the first diamond from peanut butter off his sandwich in a press for simulating high pressure atmospheres in the late 70s or early 80s. More or less on a lark. I tried to find a reference on the 'net, but the microwave diamond hoax has googlebombed it into obscurity.

The photo in the news article looks pretty similar to what I saw in an old film I saw in the late 70s. I'm pretty sure it's the same thing.

Yeah, I think I saw it in school, myself.

There was some company offering to turn (part of) your loved one's remains into a diamond...

Beats keeping an urn on the shelf, I suppose...
