Who Makes Silestone?
Silestone is manufactured by Cosentino Group, a Spanish company founded in 1979 in Almeria, Spain. Cosentino operates in over 80 countries and maintains a significant distribution network in North America. Their US headquarters is in Houston, Texas, and they run distribution centers in multiple states.
For fabrication shops, Cosentino's distribution model means you're typically purchasing through authorized Cosentino Centers rather than third-party distributors. This can be a positive (consistent quality, good technical support) or a negative (less room to negotiate pricing).
Silestone Material Quality and Composition
What's Inside a Silestone Slab
Silestone slabs contain roughly 94% natural quartz minerals bound with resins and pigments. In 2020, Cosentino introduced their HybriQ+ technology, which incorporates recycled materials and uses 99% recycled water in the manufacturing process.
From a fabricator's perspective, Silestone cuts and polishes predictably. The material is consistent slab-to-slab, which means fewer surprises during fabrication compared to natural stone. Typical slab dimensions are 63" x 128" (jumbo) and 55.5" x 120" (standard).
Silestone Physical Properties:
| Property | Value |
|---|---|
| Hardness (Mohs scale) | 7 |
| Density | 2.4 g/cm3 |
| Water absorption | <0.03% |
| Flexural strength | ~55 MPa |
| Available thicknesses | 1.2 cm, 2 cm, 3 cm |
| Standard slab size | 55.5" x 120" and 63" x 128" |
N-Boost Technology
Silestone features N-Boost, a treatment that enhances color depth and stain resistance. In practical terms, this means the surface is less porous and more resistant to common kitchen stains like wine, coffee, and lemon juice. Fabricators should note that N-Boost surfaces don't require any special sealing --- one less step in the installation process.
Silestone Pricing Breakdown
Let's talk real numbers. Silestone pricing varies based on the specific color series, your region, and the fabricator you work with.
Silestone Price Ranges by Series (2026):
| Series | Material Cost/sq ft | Installed Cost/sq ft |
|---|---|---|
| Loft | $40-$55 | $55-$75 |
| Nebula/Mythology | $50-$70 | $70-$95 |
| Eternal | $60-$80 | $80-$105 |
| Sunlit Days | $65-$85 | $85-$110 |
| Premium collections | $75-$95 | $95-$120 |
What Does That Mean for a Typical Kitchen?
For an average U.S. kitchen with 40-60 square feet of countertop space:
- Budget Silestone kitchen: $2,200-$4,500
- Mid-range Silestone kitchen: $3,200-$5,700
- Premium Silestone kitchen: $4,800-$7,200
These numbers include material, fabrication, and installation. Edge profiles beyond a standard eased edge will add $8-$20 per linear foot.
Color Collections and Design Options
Silestone organizes its colors into distinct series, each with a different aesthetic direction:
Loft Series
Industrial-inspired designs with concrete and mineral tones. Colors like Camden, Seaport, and Nolita work well in modern and minimalist kitchens. This is Silestone's most affordable line.
Eternal Series
Marble-look designs that mimic Calacatta, Statuario, and other classic marble patterns. Calacatta Gold and Statuario are consistently among the best sellers. For fabricators, this series requires careful vein-matching at seams.
Sunlit Days Series
Nature-inspired colors with a matte finish developed in collaboration with designer Cindy Crawford. These use the HybriQ+ technology and feature softer, warmer tones.
Nebula and Mythology Series
Deeper, richer colors with more complex patterning. These tend to be mid-range in pricing and are popular for bathroom vanities and kitchen islands.
Silestone Performance: What to Expect
Stain Resistance
Silestone performs well against common household stains. In independent testing, turmeric and permanent marker left no trace after 24 hours on the N-Boost surface. That said, no quartz is truly indestructible --- prolonged exposure to harsh chemicals can still cause discoloration.
Heat Resistance
Here's where you need to be honest with customers: Silestone, like all quartz, is NOT highly heat resistant. Temperatures above 300 degrees F can cause thermal shock, cracking, or discoloration. Always recommend trivets. The resin binder (roughly 6% of the material) is the weak link here.
Scratch Resistance
With a Mohs hardness of 7, Silestone resists scratching from most kitchen activities. You can cut directly on it without damage in most cases, though Cosentino recommends cutting boards to maintain the finish over decades.
Impact Resistance
Dropping a heavy cast-iron pan on a Silestone edge or corner can cause chipping. This is true of all quartz products. Fabricators should discuss edge profile options with customers --- a bullnose or ogee profile is more chip-resistant than a flat polished edge.
Warranty Details
Silestone offers a 25-year limited warranty that covers:
- Manufacturing defects
- Staining from normal household use (with N-Boost surfaces)
- Cracking due to material defects
What's NOT covered:
- Heat damage (thermal shock, scorch marks)
- Damage from abuse, misuse, or improper installation
- Normal wear and tear
- Outdoor installations (unless using specific outdoor-rated products)
- Chemical damage from harsh cleaners
The warranty is transferable to new homeowners, which is a selling point for real estate. Cosentino requires registration within 30 days of installation to activate the full warranty.
Silestone vs. the Competition
How Does Silestone Compare to Other Major Quartz Brands?
| Feature | Silestone | Caesarstone | MSI Quartz | Cambria | LG Viatera |
|---|---|---|---|---|---|
| Price range (installed) | $55-$120/sq ft | $55-$125/sq ft | $40-$85/sq ft | $65-$135/sq ft | $50-$100/sq ft |
| Color options | 80+ | 60+ | 100+ | 150+ | 50+ |
| Warranty | 25 years | 25 years | 10 years | Lifetime | 15 years |
| Bacteriostatic | Yes | No | No | Yes | No |
| Recycled content | Yes (HybriQ+) | Some lines | No | No | No |
| US manufacturing | No (Spain) | No (Israel) | No (Various) | Yes (Minnesota) | No (South Korea) |
Silestone vs. Caesarstone
Both are premium brands with similar pricing. Silestone's edge is bacteriostatic protection and the HybriQ+ sustainability story. Caesarstone tends to have slightly more realistic marble-look patterns in their top tier. For fabricators, both cut and polish similarly.
Silestone vs. MSI Quartz
MSI is significantly cheaper --- often $15-$30 less per square foot installed. If your customer is budget-conscious, MSI is worth considering. Silestone's advantages are brand recognition, the 25-year warranty (vs. MSI's 10-year), and the bacteriostatic surface.
Silestone vs. Cambria
Cambria is the only major quartz brand manufactured entirely in the USA (Le Sueur, Minnesota). It's typically pricier than Silestone and has a larger color library. Cambria's lifetime warranty is a significant differentiator. For shops, Cambria has stricter fabrication requirements.
What Fabricators Should Know
If you're a fabrication shop working with Silestone, here are the practical details:
- Ordering: Through authorized Cosentino Centers only. Lead times average 3-7 business days for in-stock colors
- Cutting: Wet cutting required. Standard diamond tooling works well
- Polishing: Silestone polishes to a consistent finish. Matte finishes in the Sunlit Days series require specific polishing pads
- Seaming: Color-matched adhesive available through Cosentino. Vein-matched patterns (Eternal series) require extra care at seams
- Remnant value: Silestone remnants hold value well due to brand recognition. Average remnant resale at $25-$45/sq ft
For shops using fabrication management software, Silestone's consistent slab dimensions make it ideal for AI-powered nesting optimization. A tool like SlabWise can help you maximize yield from Silestone slabs, potentially saving 10-15% on material waste --- that's $200-$600 saved per slab at current prices.

FAQ
How much does Silestone cost per square foot?
Silestone costs between $55 and $120 per square foot installed, depending on the color series and your location. The Loft series is the most affordable at $55-$75/sq ft installed, while premium collections can reach $120/sq ft. An average 50 sq ft kitchen runs $2,750-$6,000.
Is Silestone better than granite?
Silestone requires zero sealing (granite needs sealing every 1-2 years), offers more consistent patterns, and has bacteriostatic properties. Granite wins on heat resistance and sometimes on cost. For most kitchen applications, Silestone's lower maintenance makes it the practical choice --- but it depends on your priorities and budget.
Does Silestone stain easily?
No. Silestone's N-Boost technology makes it highly stain-resistant to common household substances like wine, coffee, and juice. In testing, most stains wipe away with mild soap and water. However, prolonged exposure to harsh chemicals like bleach or oven cleaner can cause permanent discoloration.
Can you put hot pans on Silestone?
No, you should always use trivets. Silestone, like all quartz products, can crack or discolor from sudden heat exposure above 300 degrees F. The resin binder in quartz is vulnerable to thermal shock. Cosentino's warranty explicitly excludes heat damage.
How long does Silestone last?
With proper care, Silestone countertops can last 25-30+ years. The 25-year warranty reflects Cosentino's confidence in the product's durability. The surface doesn't need sealing, and normal kitchen use won't significantly degrade the material over decades.
Is Silestone made in the USA?
No. Silestone is manufactured in Almeria, Spain by Cosentino Group. However, Cosentino has a major US distribution hub in Houston, Texas, and operates Cosentino Centers across North America. Slabs are shipped to local distribution centers before reaching fabricators.
What's the difference between Silestone and Cosentino?
Cosentino is the parent company. Silestone is their quartz countertop brand. Cosentino also makes Dekton (ultra-compact surface) and Sensa (treated natural granite). When you buy Silestone, you're buying from Cosentino.
Does Silestone need to be sealed?
No. Unlike natural granite or marble, Silestone does not require sealing at any point during its lifetime. The non-porous surface and N-Boost technology provide built-in protection against stains and bacteria. This saves both time and money over the life of the countertop.
Can Silestone be repaired if chipped?
Yes, minor chips can usually be repaired using color-matched quartz repair kits or epoxy. Cosentino offers repair services through authorized fabricators. Small chips along edges are the most common issue and typically cost $150-$300 to repair professionally.
Is Silestone good for bathrooms?
Yes, Silestone works well in bathrooms. Its non-porous surface resists moisture, and the bacteriostatic properties are particularly useful in humid environments. Popular bathroom applications include vanity tops, shower surrounds, and tub decks. The Sunlit Days matte finishes are especially popular for bathroom designs.
