In September of 1969, David Yurman was a foreman in Hans Van de Bovenkamp’s sculpture studio in Greenwich Village when another young artist, named Sybil Kleinrock, walked in and applied for a job. Ten years later, they were married, and together they built a luxury brand that would change the game for American jewelry design. As the David Yurman brand enters its fourth decade, it unveils a new collection of amulets called Elements, drawing on the symbolism of the circle. Herewith, he reveals his key components to the good life. —Ashley Baker
