    What evidence do they have that this is a diamond planet? They mention it is made of carbon but not how they know the configuration the carbon is in.

    Hrm...I thought highly compressed and heated carbon had a very good chance of configuring itself in Diamond. Now you have me thinking... I'm sure it's more complicated than simply having heat and pressure, so I don't really know.

    I think that all you really need and the right mixture of elements (unless its pure C)

    Thats how they make man made jewelry

    What exactly do you mean? Diamond, in any form, requires extreme pressure combine with lots of heat to make it form into that particular configuration. The impurities of the diamond can give it different colors and such.

    The companion planet is probably a remnant core of a ultra-low mass carbon-oxygen white dwarf. It has a minimum density of 23 g/cm^3 and a pure diamond has a density of 3.5–3.53 g/cm^3.

    I don't really care about the details, but can we call it Lucy.

    Right, thats what they do. They put a certain amount of carbon, with the right amount of impurities for color into a little chamber thing. If you can imagine all 4 sides of a pyramid with a small hole carved out at the center closing in on the soon to be made jewel at the center, it closes and compresses it to tons of psi for a few hours until the jewel forms.

    I dont remember the exact specs but it was on 'how its made' a while ago. I dont know if they make actual diamonds or if they can only make less dense jewels and birthstones. It was pretty interesting. If you go to a jeweler you can tell the real earth made ones from the lab made ones. Man made ones are much clearer vs naturally made which are much more opaque.

    Oh ok, I see what you were getting at.
