One of the largest international buyers of fine jewelry, Circa, lauds Kunz and his influence of the jewelry trade in advocating for semi-precious stones as a component of fine jewelry:
"Prior to Kunz’s tenure at Tiffany & Co, jewelry houses had favored precious stones in their jewels. He encouraged Tiffany to try new and exciting stones like Alexandrite and Morganite, making “semi-precious” stones more popular than ever. Kunz’s contributions to gemology and Tiffany & Co. have impacted the way that so many stones are viewed by the public. He brought semi-precious stones into the mainstream."
