Our Story

Five Generations of Uncompromising Quality, Value and Customer Service

Since 1910, H.L. Gross & Bro. Jewelers has been a leading purveyor of fine jewelry and diamonds. Our story began when two brothers, Harry and Abe Gross, with their bold ambition and help from their father, opened a jewelry store in downtown Brooklyn, New York. The first jewelry display was located on the sidewalk in front of their store, built upon shelves supported by sugar barrels!


Business is booming and the brothers open a larger, new store on Fulton Street in Brooklyn.


A second H.L. Gross & Bro. location is opened on Jamaica Ave. in Jamaica, NY.

An English paper by 16 year old Corrine Gross, sister of 3rd generation Howard Gross, detailing the history of her family's jewelry business. A truly interesting read.


3rd Generation Howard Gross is enlisted in the Army and serves as a radar navigator on a troop transport. After the war Howard returned and entered the family business.

The H.L. Gross & Bro. jewelry stores quickly became destinations and leaders in the diamond engagement ring business. In the 60's the Hempstead store introduced a diamond polishing wheel and diamond cutter on the premises, a first of its kind. Bridal jewelry customers would often stand in line, waiting for the opportunity to purchase a diamond from the H.L. Gross & Bro. family.


Our original Garden City, NY store is opened.

In the 80's, we were operating stores in five locations. We decided, at that time, to concentrate our efforts and resources into the Garden City store, which was growing rapidly.


3rd Generation Howard Gross with 5th Generation Brad & Matt Gross


H.L. Gross & Bro. Jewelers opens our magnificent 5,500 sq. ft. showroom directly across the street from our old location. The new flagship store almost doubled the size of the previous location.

Now ,

in their 5th generation, Brad and Matt Gross, along with their father Michael, are providing the same quality, value and service to new customers that previous generations of H.L. Gross & Bro. clients had become accustomed to.

If you haven't already, we truly hope you share the love and join our dedicated and satisfied customers in becoming part of our family!

Brad, Michael, Diane & Matt Gross
