Hillwood Estate, Museum & Gardens gave museum supporters a look at “Natural Beauties, Exquisite Works of Mineral and Gems” at a Feb. 13 preview party, “Romancing the Stone.” Tony Cammarota, Michele Hartlove and Kate Evans Lluberes co-chaired the evening. Guests enjoyed various libations, a vodka luge and buffets in the visitor center. A silent auction included such temptations as a 2021 Caribbean cruise on the Sea Cloud and a weeklong stay at a villa in France. Exhibition curator Wilfried Zeisler gave two presentations in the Dacha, where the stones from Hillwood’s collection and loan pieces are on view through June 7.
