About a year ago we had a local jeweler/goldsmith make a new wedding band for my wife that contains 9 channel-set, princess-cut F/VS2 diamonds, each weighing about .16 ct. We noticed that, in certain indirect or subdued light, noticeable dark areas or shadows appeared in the diamonds. When we showed this to the jeweler, he said that it was a normal "bow-tie" effect that is also seen in marquise or pear diamonds. It does not seem to be caused by inclusions because the dark areas disappear in stronger light. Now that I have learned more about the importance of precision cutting, I wonder if the dark areas are the result of poorly-cut princess diamonds. I would appreciate any input on this. Many thanks.
