Blood diamond vs. Moissanite, what is the big deal people?

So recently I have been learning about Moissanite. I have been trying to figure out why jewelers look down on it so much. I looked up this question and was stunned to see how many jewelers still value diamonds as "Old money" regardless of where they come from. This is the scathing article I wrote back.

Yes, Moissanite is man made but it is still the second strongest stone on the planet. Naturally, it doesn't even come from this planet! There is no way to naturally mine it!
I think that the snobbery associated with diamonds is the only thing that keeps their value up. We are too well educated to pretend that we don't know where most diamonds come from. If you could see who was mining for those diamonds, would you really care that yours was made in a lab?
Don't pretend to be naive. No jeweler can absolutely guarantee that they aren't purchasing blood diamonds unless they have mined the diamonds themselves.
Yes, diamonds are associated with old money. So is inbreeding, slavery, and mental illness. If you can prevent at least one crime against humanity, why not take it? Moissanites don't have the same value as diamonds, but that is just it. Diamonds only have the value we give them.
