Four suspects robbed the Fordham Gold Mine store located on East Fordham Road on Monday between 2:50 and 4:30 a.m.
Sources say the robbers entered an adjoining ABC Training Center through the roof.
The burglars then made a hole in the wall to enter the jewelry store through a closet.
The thieves were able to steal $1.3 million in jewelry from the store safe, police sources said.
The suspects are believed to be four men, last seen wearing masks.
