I just received my new 1.56 carat RB and was trying to view it in ''different'' lighting situations. In direct lighting i noticed how much brilliance AND fire there was. But in ''softer'' lighting conditions away from power halogen bulbs and the like, the fire seemed to almost disappear while the brilliance of the diamond was the main draw. Is this normal? I plan on trying a ''candlelight'' situation tonight and also plan on taking it in to some local stores to compare it to branded diamonds like the ''leo'' and ''hearts on fire''. But is this ''lack of fire'' in softer lighting just an individual characteristic that differs in every diamond or is there a mathematical reason for this?
