Diamond Reference Cards?

[luvmydiamonds]

I remember having a card that was sort of a ''quick reference guide'' to the 4 Cs, and other information when choosing a diamond. Does anyone know if there is something like this online I can print or where I can get one?
Thanks

It''s not exactly a reference card but it has the 4 c''s on a small sheet...you could probably shrink it.

Try ags.org, click on Jewelry Buying 101/4 c''s.

gia.edu is another informative site.
