Pop Up Jewelry Gallery (CLOSED)

New York jewelry designers Kerri Halpern of MadStone (madstonedesign.com) and Diana Heimann of Heimann & Hendrix (heimannhendrix.com) created this boutique that hawks eight different brands of fine jewelry ($150–$20,000) under one chic roof. Baubles, including Michael Raymond double-finger rings ($225) and Mauri Pioppo drop earrings ($8,900), are displayed in glass cases. Sip gratis champagne and head to the lounge area, where you can hang out on Henry Beguelin leather poufs while you contemplate purchasing Kacey K crystal necklaces ($550–$1,200) and Caleo rose-cut rings ($225–$695).
