Where is the largest diamond ever found?

Of all the precious stones that planet Earth gives us, the diamond is king, in its own right.
Its rarity, its beauty, and its incomparable characteristics, make it the most desired of gems. A real treasure for the person who wears it, and a huge responsibility for the jeweler who uses them in their jewelry creation work. Something so noble always deserves the best accompaniment, right?

In this blog I have already told you about diamonds, introducing you to some of the most famous . There I told you about the Cullinan I, or Star of Africa, which is preserved in the Tower of London: it is the largest diamond in the world, with 530.20 carats.

An exaggeration, right? Well, you may be surprised to learn that this is just a grain of sand compared to the size of other diamonds. Diamonds so immense that if they were extracted they would forever revolutionize the luxury market and even change our own perception of the value of said gem.
But that’s the problem. Extract them. I’m afraid it won’t be easy.

How diamonds are created

There are many different chemical elements on earth, one of which is carbon. But although carbon is the base element of any living being, in the earth’s crust it is very scarce (only 0.2% of it is carbon).

And it happens that carbon is an element that likes to change its look. Depending on the surrounding conditions, its structure changes: at room temperature, it usually wears the suit to walk around the house: graphite (the material with which pencils are made).
But on special occasions, carbon wears its best clothes. And they are very special conditions: a very high pressure, and a very high temperature (between 900 and 1300 ° C) at the same time. When that happens, then the carbon takes off his sweatshirt, dons his ball gown, and crystallizes into a diamond.

Creation of diamonds

This only happens at great depth (between 140 and 190 km below the surface) or under the impact of a meteorite. So if carbon is already scarce, diamond … well, we all know it.

This scarcity adds even more value to rarities like the Cullinan I. It is this scarcity that dramatically increases their price. But … what if we looked in a place where carbon was much more abundant?

But then, you can’t search underground anymore. You will have to look up at the sky.

Lucy in the sky with diamonds

No planet in the solar system is the same as another. And despite this, they all depend on the same sun. But if you have even a slight interest in astronomy, you will know that there are many suns and many different planets outside of our solar system. Wandering the Universe.

And there are planets in which the dominant material will not be silicon, as on Earth, but carbon. Graphite crusted planets (like the pencil of the gods), which in their lower layers, with the right pressure and temperature, would have miles and miles of diamond. At exaggeratedly high pressures, there could even be oceans of liquid diamond. Can you imagine diving in diamond? It would be Marilyn Monroe’s dream.

“This is all speculation,” you say. You are right. So let’s get to something proven.

Let’s forget the planets and go to the suns. There is a type of sun called “White Dwarfs” : They are old suns about to go out, whose nucleus is basically oxygen and crystallized carbon. That is to say: gigantic diamonds.

Until today, the largest White Dwarf found is called BPM 37093. But it has been renamed “Lucy”.

Because, like the Beatles song, Lucy is in heaven with diamonds. Specifically, with a 4000 km diameter diamond, and 10,000,000,000,000,000,000,000,000,000,000,000,000 from carats!

Sorry, Cullinan I. You are very talented, but you still play in the fry.
