What Sets Us Apart

GMI Quartz line includes over 40 different colors offered in both Slab & matching Prefab sizes. We have a great selection to choose from! From Jumbo and Standard size slabs to prefabricated countertops and peninsulas (up to 108"x52") which come with an ultra-seamless 45° miter edge. We have a selection of prefab colors with a 2" miter edge drop down for a more elegant and custom look without the use of slab.


We focus on providing the best customer service experience to our customers along with competitive pricing and top quality material.
