Founded in 2007, Fallon is the wild younger sister of Fenton, jewelry designer Dana Lorenz’s elegant fine luxury collection. An unabashed fan of 1980s style, Lorenz designs pieces that meld toughness with glamour: For example, the classique crystal necklace, which juxtaposes Swarovski crystals with gold-plated spikes, spike-and leather “labyrinth” chandelier earrings, and heavy-metal bangle bracelets. Fallon’s punk-but-pretty pieces appear regularly on the pages of Vogue and Elle, and the line has earned such a devoted following that Lorenz recently opened a Fallon/Fenton flagship store in the heart of — where else? — Downtown New York City.
