You need to know the crown height, crown angle as well as the pavilion depth and pavilion angle.

The stone should be checked out by an expert to see if it just made the 1.00 carat weight, by leaving on "extra fat" in the stone.

Just a quick question: do you really need a D/IF? The colour and clarity of the stone does not determine the sparkle of the diamond. However, if you chose that for the rarity factor, that is your call. F is very icy white and VS1 is absolutely eye clean for ECs

As for the rest:
Depth less than 65% lets your diamond measure much bigger (than your current 70%)
Stick to tables of less than 65%
At least VG polish and symmetry
Crown height is critical for fire in ECs (I personally prefer 12% and higher but at least 10% and upwards is fine)
Avoid girdles that are ex thin and ex thick

It sounds like the depth and table value are in the best range for emeralds accourding to several websites.

You can search yourself to see. But like was mentioned above, definitely have somebody take a look at the diamond to make sure the other proportions are just as good.

Hi Chrono, thanks for replying I do want the the D/If for the rarity factor as it is for a once off engagement ring. with regards to your other advice it is much appreciated especially the crown height.

Thanks for replying Rockdoc. some of the diamonds on offer are GIA certified but these certs don''t have crown height. so how can i tell?the other diamond they have are Hrd certs. these certs do have crown height, so sould I only go with HRD certified diamonds?

Are you going to be able to view several ECs side by side on your shopping trip? If so, then the GIA cert should not pose a problem for checking the crown height even thought it isn''t listed on the cert. You can see it with your own eyes (should be quite tall/pillowy on the top half) and even compare it to a HRD EC with a listed crown height %.
