For those interested and handy with Gemcad, theres many expired US patent designs available to draw inspiration from. Examples attached.

Type 'Gemstone' plus 'Design' into the following search engines
- http://www.freepatentsonline.com/
- http://patft.uspto.gov/netahtml/PTO/search-bool.html

Most of designs are fairly easy to work out the indexing on. The designs are intended for diamond and are best suited for CZ. With that said please respect all designs within the patent period (mostly 14 years from the patent date) and the restrictions incumbent.

Cheers,
GR
