Our History

Silestone® was founded in Spain in 1990 and quickly became a global leader in quartz surfaces. Using progressive technology, Silestone® created a superior composite of natural quartz and resins that established new standards for beauty and performance. In 2002, Silestone® became part of Cosentino®, the world’s leading producer of quartz surfaces.
As part of the Cosentino® group, Silestone® has continued to innovate and bring bold new quartz collections to market. With North American headquarters in Houston, Texas, Silestone® Quartz Surfaces are distributed to a national network of dedicated distributors and dealers located throughout the United States and Canada.
Why Choose Quartz?
Quartz countertops offers superior advantages over other surfacing materials, such as granite, marble, and laminate. Made from 95% quartz crystals combined with polymer resins, Silestone® quartz surfaces are beautifully unique while offering these benefits:
- Extreme durability – Quartz is non-porous and highly resistant to scratches, stains, heat, and cracks.
- Ease of maintenance – Requires no sealing and cleans easily with soap and water.
- Healthy and hygienic – Contains no VOCs and inhibits bacterial growth.
- Stunning selection – Available in over 90 colors and textures.
- Consistent quality – Color and pattern run all the way through the slab.
- Custom fabrication – Can be fabricated into virtually any design.
- Long-lasting beauty – Retains its original radiance for years.
Quartz countertops combine the elegance of natural stone with superior durability and easy care. Silestone® leads the industry in crafting quartz surfaces that are stunning works of art for your home.
Our Manufacturing Process
Silestone® quartz is meticulously crafted using advanced Bretonstone® technology. We adhere to over 190 quality control checks throughout the manufacturing process:
- Natural quartz crystals are mined and then cleaned, crushed, and ground into a fine powder.
- The quartz powder is blended with premium pigments and resins to create the unique color and pattern.
- The mixture is compacted under intense vibration pressures of up to 100 tons and baked at high temperatures.
- The slabs are polished to a beautiful finish, gauged to precision, and quality inspected.
- Advanced digital imaging systems ensure color and pattern consistency.
- Our surfaces are NSF certified, meeting the highest standards for food safety and hygiene.
- We carefully inspect each slab before it ships to one of our North American warehouses.
