Signed, stamped: MIMI DEE. Seasoned collectors of signed studio jewelry know that signed jewelry often maintains or increases in resale value. Do NOT be fooled! To be considered studio, the piece must be completely created from beginning to end by the artist herself or himself with very little purchased components (in this case the gemstones). What others call "studio" jewelry and sell by the 1000s after being made in some third world country, is just plain ole mass produced jewelry.
