I make jewelry for a living. It's all I have ever done. I can get certified stones in that range, anywhere from 7-12K, depending on the specs.

For instance: G, SI1, 1.25ct Round, 7k, give or take a few bucks. F, SI1, 1.50ct Round, 12K give or take. Those are stones available to me right now, and they change all the time.

The color on both of those are at the high end of what he wants, but the clarity is at the lower end. In my opinion, color is the more important factor in his specs, because the difference between SI1 and VS1 isn't real noticeable to the average eye, but bad color is.

Standard solitaire mountings, 14k, 4prong would run between $130-$160.

I normally don't just throw prices out like this, but forewarned is forearmed. At least he will know what's what. I'll help if he wants, but like I said before those stones change daily, some get sold and others become available.
