Silestone Quartz Countertops by Cosentino
The original engineered quartz, now made with Cosentino's low-silica HybriQ+ technology — on display in our Anaheim showroom for kitchens, vanities and bars.
The Silestone stand is on our Anaheim showroom floor — pull a sample and hold it to a door.
The surface that started the category
Silestone is Cosentino's engineered surface, and the stand on our floor says “The Original” for a reason: Cosentino has been making it for more than thirty years, and it is in homes in over a hundred countries. When a client asks for “quartz” without a brand in mind, Silestone is very often the name they have already heard.
What has changed is the recipe. Since 2023, Cosentino states, every Silestone colour is made with its HybriQ+ technology — a blend of premium minerals and recycled material that cuts the crystalline-silica content well below that of traditional quartz. Each colour now carries a label with its maximum: 40%, or 10% for the Silestone XM range.
Why it matters beyond the kitchen
A lower-silica slab is mostly a fabrication story: it is the people cutting the stone who benefit most, and Cosentino is plain that its surfaces are safe to fabricate when the fabricator follows proper safety measures. For you, the practical side is the same as any good quartz — a non-porous top that needs no sealing and wipes clean with warm water and mild soap.
Cosentino also publishes how the surface is made: at least 20% recycled material, 99% of process water reused, and all of the factory's electricity from renewable sources. If sustainability is part of how you are choosing materials, that is information most counter brands do not give you.
What Silestone is good at
A name you can trust
More than thirty years on the market and sold in over a hundred countries, according to Cosentino. It is the safe choice when you want a proven quartz rather than a new label.
Lower crystalline silica
Every colour is made with HybriQ+ and labelled with its silica ceiling: 40%, or 10% for Silestone XM. Cosentino had the technology independently certified in 2023.
Easy to live with
A non-porous engineered surface, so it needs no sealing and does not absorb spills. Warm water and a mild soap handle day-to-day cleaning.
Kitchens, baths and more
Cosentino designs Silestone for kitchen counters, bathroom vanities and furniture surfaces, so one colour can carry through a whole-house remodel.
Seeing Silestone before you commit
A Silestone colour name tells you very little on its own. Two whites can read warm or cold depending on the cabinet beside them, and the veining that looks subtle on a sample can dominate a ten-foot island. The Silestone stand at our Anaheim showroom lets you pull a sample out and hold it against real door styles and backsplash tile in the same light.
When you have narrowed it down, we measure, template and install the top as part of the job — see countertops for how that works. Call (714) 630-0477 or book a free design consultation, and compare Silestone with Vadara, Viatera and the rest of the brands we carry on the same visit.
Silestone countertop questions
Silica content, care, warranty and how Silestone compares with the other quartz brands in our Anaheim showroom.
-
Is Silestone real quartz?
Silestone is an engineered surface. Cosentino now calls it a mineral low-silica surface: premium minerals and recycled materials bound together with its HybriQ+ technology, giving the hardness and performance of quartz with far less crystalline silica.
-
Does Silestone need sealing?
No. It is non-porous, so there is no annual sealing and nothing for spills to soak into. Clean it with warm water and a mild soap, and use a trivet for hot pans, as with any engineered surface.
-
What warranty comes with Silestone?
The warranty is issued by Cosentino, not by us, and the terms depend on the product. We give you the written terms for the colour you choose before you order, so you know exactly what is covered.
-
How does Silestone compare with Cambria or Viatera?
All three are engineered quartz. Silestone leads on low-silica manufacturing and its long track record; Cambria is American-made and family-owned; Viatera is made by LX Hausys in Georgia. The quickest way to choose is to see them side by side in our showroom.
-
Can I see Silestone before I buy?
Yes. The Silestone stand is in our Anaheim showroom, open Mon–Sat 10am–5pm · Sunday closed. Bring a cabinet door or a photo of your kitchen and we will pull the samples that suit it.
