I just purchased a loose diamond from whiteflash http://www.whiteflash.com/loose-diamonds/round-cut-loose-diamond-3365321.htm Everything about this diamond I love except I can see a tiny speck from the side of diamond looking at the pavilion angle. I was told that the term "Eye Clean" applies to the top of the diamond, but I'm torn whether I should return it and go with a diamond that has inclusions in the middle (no speck, maybe feathers) or stick with the current one. HCA is rated 1 and I think I can hide the inclusion with the 6 prong setting that I'll be placing it in.
