There is nothing to stop people from looking for new sources of minerals. In terms of diamonds, people managed to meticulously imitate the processes that happen under the Earth mantle and recreate diamonds in laboratory conditions. So now alongside natural diamonds there are also synthetic ones, but either demand for diamonds has increased while supply remained unchanged or there is another reason we don't know, but scientists seem to see diamonds in any thing they can, even inside the planet!
The planet 55 Cancri e is the first 'diamond' planet even discovered to orbit a sun-like planet in our Milky Way galaxy. The planet is not so far away actually, it's only 40-lightyears away from the Earth, in Cancer constellation. It's twice larger than our planet and eight times heavier. 55 Cancri e consists of a molten iron core surrounded by a layer of silicon-based minerals, next goes pure diamond layer while the surface is covered by graphite. According to calculations, at least the third part of the planet is made of diamond.
This planet is absolutely unique discovery of a rich resource of diamond and it is still awaiting for people to start exploring the nearby planets. Undoubtedly, it won't happen too soon, so now what we have is natural and synthetic diamonds here on the Earth, where diamonds still remain a great investment option.
What do you think about 'diamond planet'? Do you think people will ever explore it?
