Today’s colored pencil and gouache pendant rendering is also an “oldie but goodie”. I did this one shortly after coming home from attending the GIA Quick Design Lab in NY in March 2006. Vellum paper is very useful for doing quick renderings. Vellum’s semi-transparent nature not only allows you to do handy overlays (to show different design options without having to create a whole new rendering), but also makes for great scans since the light from the scanner illuminates metal, diamonds and gemstones from beneath and adds life to them. In addition, with vellum, if you go with a light hand and are careful, you can lift off any gouache mistakes you might have made with an exacto knife.
