Pro golfer and U.S. Women’s Open champ Cristie Kerr—whose mother, grandmother, and aunt have all battled breast cancer (and are currently in remission)—has teamed up with New York–based diamond house Kwiat to create a limited-edition collection to benefit breast cancer research. Dubbed the Cristie Collection, the line incorporates Kwiat’s signature star motif with pink sapphires and colorless diamonds set in 18k rose gold. Four different styles—two pendants and two pairs of earrings—are available for purchase at Kwiat boutiques and Kwiat retail outlets nationwide (retail ranges from $2,150 to $6,600). Ten percent of all proceeds go to Kerr’s own nonprofit, Birdies for Breast Cancer.
