The best thing about designing bridal jewelry, says ­Sylvie Levine, is the joy that comes with an engagement. “I feel good knowing my work ultimately makes a difference in the lives of others,” she says. And the toughest thing about bridal design? “Incorporating such detail in a very tiny landscape,” she says. “I often wish the consumer or retailer knew [what] went into one finished piece. In total, there are approximately 150 steps from conception to execution.” Think about those 150 steps when you look at the new Sylvie Collection rings at JCK Las Vegas—“new and interesting designs that feature smaller total carat weights and boast accessible price points,” says Levine. “Oh, and double halos are the new halo! You heard it here first.”Sylvie Collection engagement ring in 18k gold with 0.55 ct. t.w. diamondsAge: 45Number of years in the biz: 25Number of employees y
