Figured I'd bump this thread back up rather than start a new one.
Long story short, my best friend since kindergarten and on-again, off-again girlfriend for many, many years and I have been talking long and hard about finally settling down together. (btw, spare me the lecture... lol... unless you know the full story, I wont listen to comments :P) I've pretty much got the vacation booked where I want to do it, but now I'm stuck on the ring. I know she wants either a blood opal or a black diamond as a main set stone. The opal I've pretty much ruled out because you can't find a ring with one that doesn't look like it belongs to either someone's grandma or is from the 14th century. In other words...

So, that leaves me with an black diamond. Now, I didn't realize how hard they are to find locally. I've checked out a few places both in Kamloops and around Richmond/Vancouver and either jewellers don't carry them or they've been dyed. Unfortunately this leaves me looking online. The goal is to find a three-set ring with a black band, though I can make do with simply finding a black diamond somewhere and a cheaper pre-set ring elsewhere and ditching the main stone for the black one. Also, it has to be untreated. However, I'm stuck on places online to look. The websites mentioned previously in this thread don't sell black ones and the sites I've found seem either a little sketchy or are companies that I don't recognize.
Anyhoo, was hoping someone might be able to help me out with this. One website that I found, Gemvara, seems decently priced and the reviews I could find seemed relatively decent, but... well, it's the internet. I find it hard trusting random websites these days.
For reference, something like this... but with only three stones (one black, two white):
