I have purchased several fancy colored diamonds with GIA reports. Some of the reports have a clarity grade, but several only contain the color of the diamond and that the color is natural. When I purchased these diamonds, I was under the impression that because they had a color grade from GIA that they also had natural clarity, with no enhancements. However, there is a seller on eBay who has some fancy diamonds for sale that have a color grade from GIA, but he states in the auction description that the diamonds are clarity enhanced. I was under the impression that GIA didn't grade diamonds that were clarity enhanced. I have emailed GIA concerning this, but I got no response. Can anyone help me with this? Thanks so much for your time.
