Detailed emerald cut proportions?

[jpcosta]

Hello all,

I am a 3D modeler willing to model a ring based on picture I found on the web. I would like to make it photorealistic but I need the correct proportions of an emerald cut to do it. I''ve already searched the internet for this and I''ve learned a lot about diamonds but I just cant find the correct information I need to model!

Can any of you please help me find a detailed (angles, distances etc) info about the correct proportions of an emerald cut shape diamond? I would be very gratefull for any tip you could give me.

Thanks in advance,
João Costa

PS: the type of cut i''m talking about:

Try the GemCalc download by Octonus... it just happens that the the free version contains the model of an emerald cut.

This is what the GC does:
