Is there such a thing as too big of a diamond?

Some astrophysicists believe they've found a 1031 carat diamond.

It sounds awfully speculative to me though, as they seem to be predicting the chemical makeup of the planet, rather than using direct observations and spectrographic analysis.

In answer to your question, no (unless you happen to be DeBeers).

Yes, most diamonds are far too big. Anything above ¼ carat is too big, too flashy, too pretentious and farrrrrrrrrr too bloody expensive.

NO! Mrs 'er indoors, you can't have a diamond ring, you'll have paste and like it or lump it!



Walking along a row of shops, one Sunday afternoon, a woman said to her burglar husband, "Look at that dress in that window, isn't it beautiful? Can I have it?" Her husband took a brick out of his bag and threw it at the window. The window broken, the man took the dress and gave it to his wife. A few shops further on, the woman saw a pair of boots in a shop window and said to her husband, "Look at those boots in that window, aren't they beautiful? Can I have them?" Again, her husband took another brick out of his bag and threw it at the window. The window broken, the man took the boots and gave them to his wife. A few shops further on the same thing happened when the woman saw a coat in a window and later when she saw a handbag in a window. Then the woman saw a diamond necklace in a jeweler's window, her husband said, "Oi! What do you think I am? Made of bricks?"

I have a half carat diamond.........







Of course it is an industrial diamond dressing stone, and cost under $10 when I bought it.

But if they are too big, it's easy to make them into smaller diamonds. All you need to do is whack it with a hammer of suitable size. I keep a large number of hammers on hand 'cos people are always showing up asking me to reduce their diamonds for them on account of them being excessively flashy.

A big enough diamond would collapse under its own weight and form a black hole.

How much would it have to weigh?

Sounds like the formula for a work of science fiction.

..... I keep a large number of hammers on hand .......

Perhaps I'll take up this habit. They would also come in handy when I want to crush my nuts.

I think a mass of carbon above the Chandraseckar limit (10^30kg) will not form black hole/neutron star and is too heavy to be a white dwarf. it will undergo a process of runaway carbon fusion and form a type 1a supernova.  once a carbon-based white dwarf gains enough mass (normally from accretion from a binary companion - or presumably through act of creation via NSF) for the gravitational pressure to raise temperature enough to fuse carbon the reaction is runaway and the blast leaves no core.

Exactly how much is an accretion urn?

That diamond planet probably isn't pure diamond; there's too much potential for other elements to be mixed in with it. I'm not even sure we could say it's all a single crystal either.
