After a career that included stints at two major diamond houses, Zahava Reismin began her line of fine jewelry—named for her first-born daughter—with a one-of-a-kind bangle bearing her daughter’s name. Exquisitely made, personalized pieces soon became her calling card, and today, each one is still designed and handmade in New York City from gorgeous yellow and rose gold, as well as silver. No surprise, some of her most stunning designs feature discrete, beautifully cut diamonds.
