Thanks for the insight
kambingkoh. Now applying learnt knowledge to practicality, I went and chose a few diamonds from WhiteFlash. Would require feedback if I'm on the right path regarding my analysis of these particular diamonds.
Diamond 1 (AGS-104100163012)
https://www.whiteflash.com/loose-diamonds/r...ond-4006518.htm- Depth: 61.6%, Table: 55.6%, Crown Angle: 34.7, Pavillion Angle: 40.7 Proportions within range, HCA: 1.1
- Idealscope image: Slight misalignment on arrow at 2 o'clock arrow, slight asymetrical arrow base at 7 o'clock arrow
- ASET image: Some blue between 5 o'clock and 6 o'clock arrow. Duller return?
Diamond 2 (AGS-104099694019)
https://www.whiteflash.com/loose-diamonds/r...ond-3994071.htm- Depth: 61.8%, Table: 55.9%, Crown Angle: 34.7, Pavillion Angle: 40.8 Proportions within range, HCA: 1.4
- Idealscope image: Very slightly smaller arrow head at 6o'clock arrow
- ASET image: Some blue between 3-4, 5-6, 7-9, 11-12 arrows.
Diamond 3, 'Pie' Carat

(AGS-104099797015):
https://www.whiteflash.com/loose-diamonds/r...ond-3999643.htm- Depth: 61.2%, Table: 57%, Crown Angle: 34.4, Pavillion Angle: 40.8 Proportions within range
- Idealscope image: Very minor dark spots in a ring around the arrows. Spread of dark spots very even so provides good interesting contrast?
- ASET image: Can see the dark "ring" more obviously here
Personal comment: My god this diamond is so symmetrical
Diamond 4 (AGS-104098959006):
https://www.whiteflash.com/loose-diamonds/r...ond-3981476.htm- Depth: 61.8%, Table: 55.7%, Crown Angle: 34.8, Pavillion Angle: 40.9 Proportions within range
- Idealscope image: Very minor dark spots in a ring around the arrows, even smaller than prev diamond
- ASET image: Some blue on the right face in between the arrows. Duller return?
