I recently purchased a loose princess cut diamond from a respected vendor on this site. I had been looking for a diamond for quite a while and thought I had found the perfect one. I even called the vendor two times and had them(2 different people at the store) look at the stone and asked what the inclusions/imperfections were and if they concerned them before I bought it. When I took the stone to get appraised and set the jewler found a tiny chip on the side of it (this was while I was standing there watching so I know he didn''t do it). He immediately said their store would not even consider setting that stone. I was completely shocked and disappointed since this was never mentioned to me. When I got home I looked at the AGS certificate and the area that was chipped was lined off. I then took it to another jewler, that is a GIA gemologist, to have him look at it. He confirmed the chip but was not concerned about it with regards to setting it. When I spoke with the vendor they said that they thought the area that was marked on the certificate was a feather and not a chip. So I guess I am asking for opinions on what to do. How does a tiny chip effect the value and the durability of a princess cut diamond? I bought the diamond and the vendor priced it based on it not having a chip. When I asked if they would consider adjusting the price to reflect the chip they said it would not change the price because it is on the certificate (mind you they thought it was a small feather not a chip when they priced the stone). Does this sound right? I really like the diamond but am now not sure what to do. Should I be concerned by the small chip and if I do decide to keep it should the price be adjusted to reflect the chip? Any help/opinions are appreciated.
