A 30-second smash-and-grab heist in The Bronx netted a clutch of thieves more $2.15 million in “high-end diamond jewelry” during a wild, caught-on-video robbery, police say.

Surveillance video shows a suspect, clad in a white T-shirt and a black cap and wearing sunglasses, acting like a customer when he’s buzzed into Rocco’s Jewelry on Webster Avenue in Fordham around 2:30 p.m. Friday, cops said.

But instead of going inside, the man then let his three masked cohorts rush through the door, video shows.

A hammer-swinging man then smashes the glass cases while the other thieves pulled out trays of pricey baubles, cops said.

“Once inside the store, the three individuals used a hammer to smash open the display cases and removed a large amount of high-end diamond jewelry,” police said.

The jewelry was placed into bags that were carried by the thieves, who fled the location on foot heading southbound on Webster Avenue, cops said. 

The caper lasted about 30 seconds, the security footage shows.
