hi brian,

if you really want to dig into gemstone design, be sure to check out this website:

http://www.rockhounds.com/rockshop/gem_designs/design_index.shtml

a rather amazing collection..


actually, i did a prototype based on such a design...(and with the help of moi)..

workflow would be something like this:

gemcad->rhino(dxf to 3dm)->moi->pepakura->cutout model..fiddling around with some foils and fresnel-things





cheers,
marco
