Fluorescence affect idealscope result?

[CaliCaratHunter]

I''m "hunting" for a round brilliant (probably H&A) with ~ the following stats: 1.4 - 1.6 ct D-G VVS2-VS2

In comparing the two stones linked below, I see a rather dramatic difference in the shade of red given by the ideal scope.
Can someone explain this to me?
Does it have anything to do with one having no Fluorescence and the other "medium blue" ??

No. It's just differences in lighting and setup. Stronger backlighting, the diamond placed closer to the source or different camera exposure settings result in lighter hues. Bear in mind that reflector imagery is best for getting overall impressions. Nuances in overall hue are dependent on setup. Both of those setups are good for seeing the overall pedigree of light performance in the diamonds.
