When Eric Zelwian, owner of Gemini Cut Glass (55-02 37th Avenue, at 55th Street, Woodside; 718-397-8200 or geminicutglass.com), claims that his skillful workers “can handle any chandelier,” he’s not kidding. Among the dozens of antique lighting fixtures currently awaiting repair in Zelwian’s workshop is a dazzling 4,000-pound chandelier that once hung in the Paris Opera and is now earmarked for a bank. The company’s client roster includes Baccarat and Waterford, top-tier auction houses, and scores of picky designers and architects. Gemini will rewire a simple sconce for $35 or custom-build your fantasy chandelier for between $1,200 and—if you’re like Donald Trump, who’s a regular customer—tens of thousands of dollars.
