The four employees were not seriously injured.

New York jewelry heists

Jewelry store robberies are rare and becoming even rarer. In the first six months of 2019 , there were 59 total jewelry store robberies nationwide, down from 105 in the same period last year, according to the Jewelers’ Security Alliance, a trade association that tracks jewelry crimes for retailers and the police.

Here are a few notable New York City jewelry store capers from prior years:

2016: On New Year’s Eve, three people stole about $6 million in goods from a wholesaler in Midtown specializing in rare pink and yellow diamonds.

2014: A person posing as a deliveryman entered a store in the diamond district with a gun and made off with more than $500,000 in cash and jewels.

2013: A man smashed a display case in the lobby of the Four Seasons Hotel in Manhattan and grabbed more than $166,000 worth of jewelry.

2006: Masked gunmen with a crowbar broke into a store in Bay Terrace, Queens, and stole at least $500,000 worth of diamond engagement rings.
