A long tradition of custom craftsmanship

25 years ago, Gem Marble & Granite Corp. was founded by Vincenzo and Giuseppe. They ran their fabrication shop by working hand-in-hand with their stone craftsmen, maintaining the industry-leading craftsmanship and attention to fine detail.

Today, we still pride ourselves on these same qualities in every aspect of our business from supply to fabrication and final installation.

From New York City to Montauk and beyond

Located in the center of Long Island, Gem Marble & Granite Corp. is one of the largest fabricators of marble and granite in the tri-state area. We serve customers from New York City to Montauk, Shelter Island, Fire Island, New Jersey, Connecticut, Rhode Island, and Massachusetts.

We fabricate, template, and install:

• Countertops and vanities
• Integrated stone sinks
• Monolithic fireplace surrounds
• Tub tops, stone veneers, and more

Creations that are built to last

Does it ever seem as though things are "built to crumble" these days? It seems as though nobody values expert care and craftsmanship. At Gem Marble & Granite Corp., we still strive to produce top-quality materials using old-world skill.
