Portrait With Jewels

A woman decided to have her portrait painted.
She told the artist, "Paint me with diamond earrings, a diamond necklace, emerald bracelets and a ruby pendant."
"But you are not wearing any of those things."
"I know," she said. "It's in case I should die before my husband. I'm sure he will remarry right away, and I want his new wife to go nuts looking for the jewelry."
