I say, show respect for those with opinions. Maybe diamonds in space are 100% useless, I would be totally willing to accept that fact. I'm only upset at the rudeness and name calling.

If, in 20 years, we find a use for diamonds in space, then yes, they would be much more valuable than Earth ones since you don't have to transport them to space. Additionally, it seems quite likely to me that a strong compound like diamond would indeed have its use in space.
