I have a D colored 1.25 diamond. It is in a ring with channel set small round diamonds. There are 17 totaling .34 cts. Those are G-H in color. I noticed a big difference in color between the big one and the small ones. Technically I should because there are a lot of colors between D and H. But what I was always told was G-H diamonds are near colorless and when mounted, especially small ones, you can''t tell the difference. Does anyone else notice a difference? I was just wondering. I don''t think its a big enough problem for me to do something about it.
