I have a personal preference towards radiant cut diamonds which are generally perceived to be of lower cut quality, so I was surprised to walk into a Harry Winston store and find radiant cut diamonds but be told that they don’t sell princess cut diamonds. Does anyone know why this is the case? Also, their diamonds look impeccable. Is this just store lighting or are the diamonds really that amazing? If it’s the latter, how would one go about identifying spectacular fancy cuts that are the same quality as Harry Winston?
