Our Story

In 2015, Genuine Quartz launched and leased our first warehouse in Pomona, California. We started business to provide top quality Quartz slabs and prefabricated countertops to business professionals in the construction and remodeling industries.


With our hardworking team, offering incomparable customer service and exceptional products, Genuine Quartz quickly outgrew our first 26,000 square foot warehouse and became one of the leading Quartz distributors in Southern California in just 4 short years.


In 2019, we converted our name to Genuine Materials Inc. so that we were not limited to only supplying Quartz material, but a variety of other stone products and supplies to our commercial and residential customers.


In October 2020, we moved to our new 34,000 square foot headquarters in Ontario, California. Since then, we have continued to supply our customers with remarkable service and products which has sustained our growth as one of the top choices for construction and remodeling needs.
