Within the Fleur-de-Lis earring is a Kentucky Cluster of real diamonds. The "Louisa Villea" is the only oil painting ever to incorporate actual gems within the painting.
Louisa is fictional. She represents the blending of the race, creed, and color that makes Louisville, Kentucky a world-class city. If you are using a tiltable LCD monitor you can actually change her ethnicity to see how she represents all of Louisville's citizenship.
