I gave my GF one of those attached a ring shaped formation a couple of months back on holidays. Now she keeps talking about a wedding, not sure what she is on about. Diamonds are seriously not rare the gas giants have masses of them also but interesting to know the latest finding on Earth.
if there is sooo much diamond, that means it is virtually worthless. so it will be very foolish to drill that deep to harvest the worthless diamond.
Not if you're the only one who could do it. You could then parcel it out. But we're talking sci-fi. For now.
If Musk reads this he will make quickly a machine that can achieve the mining. The Boring Company?LOL
