I have noticed that my FIances ring looks very yellow/tan whenever we go into Jewlery stores like Longs, Descenza etc. At no other time does her ring look this way. They all seem to have similar lighting. I would think that Jewlery stores wouldnt want their diamonds to look yellow. Her ring is an off graded I color which is being returned(the person Im dealing with is still in the hunt for a replacement). It took us 3 months to even realier the problem with the color because everywhere else it looked white. Has anyone else noticed this when they go into Jewelry stores??
