Spence is aimed at people who don't know what is going on, haha
When I initially was looking around I went into their store they showed me cloudy diamonds that had black spots and terrible cut and colour; then they went on to show me a bunch of low grade diamonds which of course looked amazing in comparison. I can see how they sucker in people that don't know any better.
After they were done the sales pitch I gave them a list of specs I wanted for a diamond. They didn't have anything in the store that was that "high quality", only diamonds in Vancouver they could special order in. My jaw nearly hit the floor when I saw the price, it was quadruple that of other places.
I would have gone this route if I had to do it again
EDIT:
Actually, the price isn't all that great?
