Cops are searching for two men who held up an Upper East Side jewelry store with hammers Sunday.

The men entered Travers Fine Jewelry at 962 Madison Ave. around 4:30 p.m. with their hammers and ordered workers not to move, police said.

They then allegedly stole $15,000 worth of jewels from a display case and fled.

No one is injured in the heist.

The first suspect, who was wearing a black jacket and ski cap, is described as 5-feet-9 inches tall and 165 pounds. The other suspect, who wore a gray hooded sweatshirt, is described as 6-feet-2 inches tall and 200 pounds.
