My girlfriend is into making jewellery. I have started to design some 3d
animated rings etc. for her to copy one day!
Does anyone know of any POV code closely describing the optical
properties of typical gemstones (eg. diamond, sapphire, opal, moonstone
etc.) as well as some traditional cuts (eg. classic diamond facets,
hemispherical/cabochon<sp?>, quartz-like cleavage, etc.)?
Many thanks in advance

I have a scene file of what could be considered amateurish gemstones at best.
If that sounds okay then I'll send it over. There's a sapphire, opal, ruby,
emerald, diamond (the "cut" stones are CSG of plane) and even a terribly bad
tigers eye. None being based on reality of course.

Hi Matt!
Not exactly POV-code, but I found a lot of useful info on gems on this
(http://mineral.galleries.com) site where I also found many of the
updated IOR-values. I know it's the "backside" of a commercial site
but it is very usefull. They got pictures, crystal-structures,
color-variations, chemical formulae etc. Worth a look.

You should have included this link with your last note:
http://babelfish.altavista.digital.com/
That way those of us whose French is very dated can read about "le
brilliant"
