I just wanted to post a brief note saying I bought a ring from D.NEA / AOTC for my girlfriend/fiance, Jana, and she's quite happy with it. I proposed with it last Saturday and she said "yes" 
The diamond is a 0.74CT, Fancy Intense Blue, round brilliant, VVS-1. The ring is Pd 950 (95% palladium), with 5% ruthenium. I've attached a photograph from D.NEA.
Some key notes from my purchase experience:
1) Why buy synthetic? Summary: I'm not helping De Beers, the environmental impact of producing a synthetic diamond is significantly less, there are no human rights issues, the cost of a synthetic blue diamond is orders of magnitude lower than an equivalent mined diamond, they're unusual and I'd never seen a synthetic diamond before, I appreciate the technology it takes to produce them, and they have a "birth date." I hope that's clear
2) Why not buy synthetic? No good reasons in my view
3) D.NEA uses EGL-USA by default. It's just as well. I had the diamond evaluated at GIA and EGL-USA and found GIA's report less useful. EGL-USA simply provides better lab reports for synthetic diamonds. Moreover, GIA graded the diamond as "Vivid blue," and its clarity as "VVS." No 1 or 2. On the basis of this anecdote, there's no evidence that EGL-USA provides softer grades. More importantly, GIA's imprecise clarity grade and lack of cut information are inexcusable in my view. I'd be happy to post scans of the EGL-USA and GIA reports for comparison if anyone is interested.
4) I'd like to see a study or discussion about how to cut colored diamonds. Traditionally, it's my understanding that colored diamonds are cut to maximize their apparent color. However, reduced light return, brilliance, and fire would seem to be the result. Given that synthetic diamonds can be arbitrarily saturated -- what would make the most sense?
5) D.NEA was a great company to buy from, and I'd recommend them without hesitation. Their website is http://d.neadiamonds.com
I wrote an article that provides considerably more depth than this and posted it on my personal web page. However, PriceScope prohibits links to personal web pages, so I will simply say that my name is Matthew J. Renzelmann and that the article is available via the first Google hit in case you'd like to read more. Disclaimer: I'm presently a student at the University of Wisconsin in computer science and thus don't know much about gemology -- but I do know that Jana approved of the ring
