I've seen a lot of diamonds in my working career and when I see the diamonds that come from Stuller the quality is always so high.  It's as if they aren't grading them properly because they're such high quality stones.  The I1 stones come out looking like they're SI or VS stones especially in the melee.  And I'm so impressed with the high quality and the consistent high quality of what you sell.  The cuts are excellent, the color is right on it makes me feel good as a jeweler to be able to sell your diamonds to my customers because the quality is so high. I have confidence in the stone that I'm selling that it really is graded as the cert says.  Not everyone sells the same stones that they have on the cert.  They tend to overvalue the quality of their diamonds and nothing is inflated and in fact the quality seems to be higher than what the certs even say. So I absolutely can trust it as a goldsmith and a diamond center that the stones are absolutely the best stones I could be giving my customers.  A great value.
