Estimating Crown Height [Emerald]

[chad_c_u]

Is there any mathematical relationship between diamond measurements on an emerald cut that would allow one to estimate the crown height%. The Gia report on the diamond leaves that out for the 2005 diamonds.

This is the diamond I am looking at.

Weight: 1.16 ct
Measurements: 7.39x5.24x3.30
Color: G
Clarity: IF
Depth % 63.0%
Table % 65%
Symmetry: VG
Polish VG
Girdle: Thin to Medium
Culet: None
Fluorescence: None
L/W ratio: 1.41

All of the ratio''s fall within the 1A class, but I have one variable. Any Mathematical way of making an estimation using trig?

no there isnt enough info.
If your buying it online be sure and get pictures.
A side view would answer the crown height question if the seller doesnt have a sarin machine.
