I have bought a diamond with the following hearts light performance pattern. As can be seen from the below image a yellow region appears close to the center of the Hearts image. I have not observed this before and would appreciate it if one of the experts here can help me understand this. After multiple tries I was able to find an area in the 360 video which can be the source of the yellow region. How can this affect the value of the diamond? How come this does not appear in the GIA report? Furthermore, as can be seen from the inclusion pattern the diamond has feathers in multiple locations, should I be worried about the feathers? Overall do you think this diamond is a good choice?
