Julie Chen is married to the CEO of CBS, who was born into a Jewish family. I think the red string is of Hebrew origins (Kabbalah). According to Wiki, she is also a Yogi, and I think the beads represent different spiritual and energies. My mother has an agate energy bead bracelet, she says she feels calmer and more productive when wearing it. She made her own bracelet with stretch cord. You can probably find them in mystical/new age shops or do a search on chakra, mala or ayurvedic beads When I was exploring spirituality, I was very drawn to the Celtic folklore and wore a Celtic cross and a Celtic charm.
