About Silestone

The quartz pioneer, reformulated as a lower-silica hybrid mineral surface.

Silestone, also from Cosentino, has been in kitchens for over 30 years and was one of the original quartz surface brands. It's since been reformulated under Cosentino's HybriQ+ technology, blending premium minerals with recycled materials to reduce crystalline silica content while keeping the hardness and design range that made it popular in the first place. Cosentino also runs its Silestone manufacturing on renewable-sourced electricity, which is part of why the brand pairs well with clients specifically shopping for a lower-impact quartz option.

  • HybriQ+ technology — lower crystalline silica, at least 20% recycled material
  • Built-in antimicrobial surface protection
  • NSF and GREENGUARD certified
  • 70+ colors across three finish options
  • 25-year limited residential warranty
  • Manufactured using renewable-sourced electricity

Recent Work

Silestone installations from our team.

Silestone-style white quartz bathroom vanity, NH

A clean, antimicrobial-friendly Silestone-style vanity top — a popular pick for family bathrooms.

Silestone-style quartz laundry folding surface

A quartz laundry-room folding surface — low-maintenance enough to handle daily household traffic.

Good to know: The HybriQ+ reformulation was partly driven by growing awareness of silicosis risk during fabrication — lower silica content is a genuine worker-safety improvement, not just a marketing angle.
Common Questions

Silestone FAQ.

What's different about HybriQ+ Silestone versus older Silestone?
HybriQ+ reformulated the material to use significantly less crystalline silica — down to as little as 10% in part of the range — by substituting recycled glass and other minerals, while keeping the same hardness and performance.
Does Silestone really resist bacteria?
Silestone includes built-in antimicrobial protection integrated during manufacturing, which helps keep the surface cleaner between normal cleanings — though it's not a substitute for regular cleaning.
How long has Silestone been around?
Silestone has been manufactured for over three decades, making it one of the longest-established quartz surface brands in the industry.
Is Silestone the same company as Dekton?
Both are made by Cosentino, but they're different materials — Silestone is a hybrid mineral/quartz surface, while Dekton is an entirely different ultracompact sintered material. We can help you decide which fits your project.
