Zoe and Hilary have been friends over the years and during a chat with the Los Angeles Times back in 2012, Zoe revealed that Hilary even made her a few pieces of jewelry with her son Skyler's name on them.

"For me, I have never stopped wearing big jewelry, some bigger than my appendages," Zoe told the publication. "But it’s not for everybody. And since my son has been born, there are more delicate things that I sleep in and don’t take off."

"Anita Ko made me a necklace that’s a vertical bar engraved with my son Skyler’s name and birth date, and Hilary Tisch made me a couple of delicate pieces with his name on them too," she added.

"She, like so many others, bravely fought the disease of depression for as long as she could," the producer added. "We love and will miss her dearly. Our family is utterly heartbroken and is mourning its tragic loss. We ask for privacy during this very difficult time."

Hilary was a jewelry designer and gemologist, and one of the founding partners of Doen, a Los Angeles-based brand.

In her biography for the company, the creative consultant said that she split her time between LA and Aspen, Colorado, with her dog Pearl.

Hilary said that in addition to antique jewelry, her passions included "discovering and collecting vintage furniture, objects and beautiful clothing both old and new. I am usually drawn to unique and special pieces that appear modern despite their age."

Hilary also volunteered with the nonprofit Operation Smile with her father and siblings to provide free surgeries to those with cleft lips and cleft palates.
