Please help to rate 3 diamonds. Shallow crown angle

[Ashleigh]

on 2 diamonds. Which diamond will have more fire as compared to brilliance? Which would be your 1st, 2nd, 3rd choice and why?

All are round H&A.

Diamond 1:
Table: 55.1%
Depth: 61.9%
Crown angle: 33.9
Pavilion angle: 40.8

Diamond 2:
Table: 55.6
Depth: 61.4
Crown angle: 34.1
Pavilion angle: 40.8

Diamond 3:
Table: 55
Depth: 61.2
Crown angle: 33.9
Pavilion angle: 40.8

Many thanks.

These have similar crown angles and table sizes, so I think these would all give a similar "look" of slightly more brilliance and slightly less fire, as opposed to a Tolkowlsky cut or a Fiery Ideal Cut (FIC) - if you prefer fire, you need to look for crown angles of 35 degrees and higher - do a PS search on FICs to get the cut guidelines.

But assuming these are the only choices, is there one more fiery than the other? The one with the greater crown angle doesn't have the greatest depth. I'm not certain the role of depth in fire.

And these are AGS certs. Any idea how the rounding is like?

Pics?

Great pavilion angle across the board, should result in great volume of light return, but as indicated the diamonds are more likely to exhibit more brilliance than dispersion. However lower girdle halve and star facet length measurements also come into play, so right now you're only providing insight into part of the puzzle. And are these the only options that you are being offered? Nothing with a slightly higher crown angle? e.g. 34.3 - 34.9 degrees with that range of pavilion angle offset...
