In partnership with Stephen Silver, Chopard, the Geneva-based house of jewelry and timepiece design, announces the opening of its pop-up boutique at the Rosewood Hotel at Sand Hill, located in Menlo Park, California. The hotel draws Silicon Valley's leading technology executives, who will appreciate the extraordinary gifts for the most important people on their holiday list. The new store, which will be open through December 31, is the only temporary Chopard retailer in the US.
