Police continue their search for two men who made out with an unknown amount of jewels in a brazen smash-and-grab at the Four Seasons Hotel in midtown over the weekend.

John Kennedy is the president of the Jewelry Security Alliance, a non-profit trade association that helps the jewelry industry with crime information. He says people who commit these sorts of crimes are not trying to be subtle.

"They might have a hoodie on or they might have coat pulled up or whatnot, but often they're not masked and they're very bold," he said. "It may happen in 25 seconds and they're out of the store."

Neither of the suspects wore masks. The pair walked into the East 57th Street hotel around 2 a.m. Saturday and used a sledgehammer to shatter a jewelry case in the lobby.

The NYPD tells the New York Times that one of the suspects grabbed a number of glitzy items including watches, a pendant and a chain valued at more than $166,000.

Kennedy says items stolen in these sorts of robberies can be sold overseas or fashioned into other pieces. 

"In the case of watches, it's not easy," he said. "But in the case of jewelry, if there diamonds or precious stones, someone will pop them out and it will become a different item."
