Yes, I know this sounds sacrilegious to suggest accepting their company provided report but for me, it depends on the price point as well. If you don't mind and it isn't expensive, I'm fine with it. But considering that you are looking for a 3 to 5 ct stone and it's from NSC (price wise - I'm not implying their stones are heated), I'm guessing it will cost a few $K and at that price point, I am more likely to want independent verification / proof.

Chrono|1374164297|3485569 said:No wonder the name is familiar. This looks like a memo from Christian Dunaigre's "new" independent consulting company / lab. He started out his career with AIGS, then moved on to Gubelin for 10 years before branching out on his own. I am not personally familiar with his company but based on his reputation, I would think it as very reputable.
