A new cherry blossom queen started her reign at the Cherry Blossom Grand Ball on Friday night. Samantha Olson, originally from South Dakota and a current graduate student at George Washington University, was chosen by the spin of a “wheel of fortune.”

For her coronation, Samantha was adorned with an opulent crown from Mikimoto, made of two pounds of gold, 1,585 pearls and an ermine band.

The 69th annual ball, hosted by the National Conference of State Societies, celebrated Japan’s gift of cherry trees to the United States 105 years ago. After spending the past week together nonstop, the princesses — representing each state, the District of Columbia, territories, Japan, Russia and the Philippines — seemed much more like sisters than rivals. After the formal program, the princesses danced through the night to music by the Rhythm Method Band.
