The Montgomery County Sheriff's Office told Eyewitness News the crooks stormed the Helzberg Diamonds store just before 11 am.
The jewelry shop is located inside The Woodlands Mall near the food court.
Detectives said one man tried to spray paint over a security camera while the other smashed into glass cases. They hauled away around $75,000 worth of jewelry.
Captain Bryan Carlisle with MCSO said a witness tried to stop the criminals.
