A pair of thieves shot the the owner of a Bronx diamond boutique on Saturday during a brazen robbery attempt, police sources said.

The men approached the 57-year-old worker at Marilyn’s Diamond Collection in Riverdale, and demanded the bling at around 12:15 p.m., cop sources said.

One of the thieves then shot the owner once in the gut, and fled the Johnson Avenue store in a tan Ford Explorer, police sources said.

It’s unclear if the duo made off with any precious gems.

The victim was taken to St. Barnabas Hospital in stable condition.
