Gem Marble and Granite Corp

Extremely happy with our new kitchen countertops! Joe helped us pick out the perfect quartz slab to complete our design. Quick, efficient, and met our deadline! We love to just sit and admire how beautiful it really is.

Right from the start we knew we made the right choice in choosing Gem Marble and Granite. After meeting Joe Bellone project manager things moved smoothly he was courteous and his new ideas made the day. Within few days Gems installer Marvin came and measured without removing the existing vanity top, that was very helpful being able to use the sink. Very quickly Marvin was back with the new top and back splash, he and his crew were very professional and polite. Very quickly they installed the top it fit perfectly and and look beautifully!!! Gem, Joe, and Marvin they're the best!!!! I definitely recommend Gem Marble and Granite!!!

Don't do it !! They put a seam in my 7k countertops that doesn't match and says it looks good. Terrible. Take your hard earned money elsewhere

Joe and his crew did an awesome jobs installing kitchen, bathroom and butler pantry counter tops plus fireplace marble. All aspects of the job were done professionally and in a timely manner. Would definitely recommend Gem Marble and Granite.

Gem was highly professional, honest and delivered Cambria Quartz when promised, even with delivery obstacles for delivery to Fire Island. Gem's installers were professional and courteous. Gem's countertop templates were perfect and the countertops fit exactly as planned. We highly recommend Joe Bellone at Gem!

From the start Gem Marble has been great. We walked the yard and warehouse to look at all their beautiful slabs to find the best match for what I wanted for our rustic bathroom remodel. We (my husband and myself) were doing this ourselves and had very specific things we were looking for. Well, we found the most beautiful "Rainforest" marble and wanted it to look aged, weathered, and not shiny and boy did they do a great job You can feel the veins in this marble, We could not be happier with how it turned out! Thank you Joe and everyone at Gem that made our dream bathroom come true.

We, unfortunately, dealt with Joe for our basic 60" vanity top. It was a complete disaster from start to finish. Workmanship and especially customer service are completely lacking. We will most definitely be looking elsewhere for the rest of renovations. This was our awful experience: It took a week for Joe to get a hold of the template guy to schedule an appointment for which he never showed up. Joe, of course, did not take the blame or apologize for the no show. When the measurements were finally taken we were told by Joe that it would be less than 2 weeks to fabricate. Four weeks later and after countless unanswered messages from Joe, we finally got the word our counter was ready (by calling ourselves- don't expect them to do their job). We scheduled the install and they showed up without the back splash because, according to the installer, they broke it while cutting (when we asked Joe why we were told it was all done if it had broke while cutting he changed his story saying it broke while loading onto the truck). We were underwhelmed with the product and installation. There was a large gap left between the wall and counter top. We complained & Joe said the side splash (which we did NOT want or order, but apparently paid for) would cover it- we had no choice but to use the side splash at this point. We just got the back splash and side splash installed and they are too short for the counter top. I expected everything to be perfect considering it took a month for a 60" vanity top. Precision is important in this industry, but apparently not to Gem. The polish on the stone is not good, the measurements taken were not correct and Joe was an absolute horror to deal with. They take no responsibility for their mistakes and they did not reduce the price for our troubles and the poor quality of their stone or offer us a corrected back splash for their measuring error. Save yourself a lot of stress, wasted time and money... go elsewhere.

Gem just installed our quartzite countertops for our kitchen renovation. Joe was so very helpful with his knowledge and suggestions, explaining every detail. He "stood up" for us when we needed a helping hand. His installers, Marvin and Oscar, are excellent! They are prompt, polite and clean. They said "if you see something - say something and we will address it". Such an easy company to work with! I will recommend Gem to everyone. My countertops are amazing! Thanks Gem!

Gem Marble & Granite Corp. in Ronkonkoma, NY has once again done an outstanding job in our home. We used Gem in the past for a fireplace surround and recently for our kitchen countertop. We were extremely pleased with the entire process from choosing the material to measuring, and finally to the installation. We worked with the owner, Joe, who was most knowledgeable and helpful as we made our choices and decisions. I would highly recommend Gem Marble to anyone! Gem is truly a "gem!"

Outstanding customer service (Joe), nice clean showroom, great selection of countertops, perfect measure and fit, reasonable price, and the finished countertops are exactly what we wanted. Thanks Gem!

Everyone I dealt with was extremely professional, from Joe, who helped me in the showroom to all of the workers who worked within my home. I felt completely at ease throughout the entire process. I am so pleased with the work, my new counter tops are beautiful.

We purchased a new condo that came with a fireplace included with the price. I wanted the fireplace be a focal point of my Den and asked the seller to leave off the mantel and just install the fireplace. I went to a company that only deals with fireplaces and mantels to shop for something different, and the fireplace company suggested I go to Gem Marble and Granite. Joe Bellone of Gem Marble was the person we worked with, he was knowledgeable and informative. Although he speaks a very technical language he was always willing to take his time and work with us until we fully understood the process and what it was we would be working with when it comes to stones. The finished product is lovely, more then I had hoped for. The seams are flawless and difficult to detect. The concept that I had in mind was a 3 dimentional look. Gem was able to make that happen and the stone was prepared all in one piece. I would recommend Gem to anyone with an imagination for the impossible. Gem can make what you believe is impossible, possible.
