You can get them here.

De Beers doesn't have as much power as some people think. There is resistance to synthetic diamonds in common jewelry stores because a cheaper diamond doesn't give them as much profit off the markup as a more expensive diamond.

Yes.

When I first looked it up I'm pretty sure their web site said they had the same chemical formula as diamonds (whatever that means, diamonds always have impurities). I couldn't find that particular claim but these do cut glass and look very good. Beyond that I can't test them. They definitely aren't cubic zirconia.

Moissanite is about 10-20% cheaper than mined diamond. That suggests to me that the moissanite people are taking advantage of their monopoly.

Ehh, sorry those Diamond Nexus Labs things are not diamonds. Probably cubic zirconium. Look at the chart: http://www.diamondnexuslabs.com/jewelry/informatio n/chart_comparison.htm
An artificial diamond would still have a hardness of 10, and you can see they never actually call them diamonds, instead DNL gems.
You second link goes to a company that measures gem light performance but doesn't sell any gems as far as I can tell...

It's not a good article and it's not something that just happened.

See this for a good article (and it's from 2003).

You can even buy them here or here, or just read the wired article and check up on the companies mentioned in it.

Good observation. http://diamondnexuslabs.com/jewelry/information/ch art_comparison.htm
also indicates that the hardness does not equal that of diamonds, in fact falls behind Moissonite as well.

Sigh. "Creators of the world's finest diamond simulant gemstones" -- those aren't actual synthetic diamonds either! They're actually cubic zirconium. At least this company, unlike Gemolite, is slightly more forthcoming about it (they never actually use the words "cubic zirconium," which a normal person might recognize, but at least it's obvious that ZrO2 isn't the same as pure carbon).

See: http://diamondnexuslabs.com/

They have been selling clear man made diamonds for a year at least.
