I recently purchased an ideal-cut diamond with the following specs. Its IdealScope image was almost perfect, suggesting VERY little (if any) light leakage.
1.62ct Round Brilliant H VS1 AGS0
7.64 x 7.66 x 4.64mm
Depth: 60.5%
Table: 56.7%
Pavilion Angle: 40.9
Crown Angle: 34.7
Culet: 0.9%
Girdle: 1.2-1.7%
Polish: Excellent
Symmetry: Excellent
Flourescence: None
HCA Score: 1.6
My only reservation prior to purchase was the H color, but I was assured that the diamond (with its excellent cut) would face up very white. Most of the time it does...but, in some light, I swear it glows YELLOW! Yikes! Given the H color, I expected "off-white" or some tinge of color from some angles in some lighting, but I definitely did not expect a "fancy" yellow glow under incandescent bulbs.
Can anyone tell me whether the vivid and uniform yellow color I see is the result of the H color of my stone or its high level of light reflection (or some combination)? The stone looks very white in direct sunlight and under flourescent bulbs but appears especially yellow (gold really) under the recessed lights in my kitchen. Help!!
I have seriously considered returning what I think otherwise is a truly exceptional stone...If the dramatic change in color I see is "normal" (that is, happens with stones of all colors), I don''t want to overreact. It''s just hard to believe the same diamond can look SO different from time to time!
