diamcalc wouldn''t tell you anything as the numbers are badly rounded and we don''t know the optical symmetry of the diamond.
The numbers look like it might be a decent 60/60 style stone but there is no way to know for sure from the numbers.

Why do you need diacalc for these anyway? The dimensions are so rounded off in GIA reports that HCA should be able to give a rough idea on the performance of the stone.

Unless you have the detail scan, values for each facet, diacalc is just going to produce a general symm representation anyway.

I thought you already bought a diamond... did you not keep it in the end?
