The New York City Gem & Mineral Show is hosted by The New York Mineralogical Club and Excalibur Minerals.
March 7-8 at the Holiday Inn Midtown, 440 West 57th Street.
Bring cash, take a walk through the area first, and on your second tour start asking questions, and on your third start buying.
Bring your own canvas bag or backpack since you will be leaving heavier than you were when you entered.
Make a day of it in Manhattan. You are not far from the American Museum of Natural History or the American Folk Art Museum.
