One of the jewelery artists I've come across who has really impressed me is Jamie Spinello.
I love her use of form and texture! Her designs expore both geometric and organic shapes, creating an almost tribal look that still manages to be elegant.
She excels at transforming "alternative metals" - things like copper and brass and stainless steel (considered by many to be inferior to shiny gold and silver) into sophisticated pieces fit for a queen, or perhaps a warrior priestess from some exotic alien culture. :)
She also creates stunning 3-D works in cut paper and plastic, as well as painting, drawing and collage pieces.

The piece pictured above is my favorite!!!
