Quartz countertop brands compared: Cambria, Caesarstone, Silestone, MSI and the rest

All mainstream quartz brands use the same basic recipe, roughly 90% ground quartz bound with resin, so a hot pan or a glass of wine affects a $55 per square foot slab and a $130 slab in much the same way. What the brand changes is the design library and how realistic the marble looks, how consistent one slab is with the next, slab size, warranty terms, silica content, where you can buy it and the price. Cambria, Caesarstone and Silestone sit at the premium end. HanStone and Viatera sit in the middle. MSI Q and store brands are the value end. For most kitchens the fabricator you hire matters more than the brand you pick.

What's changing in 2026

• Where a brand is made now affects its price. Since August 15, 2026, a U.S. safeguard tariff of 25%, or 50% above a quota, applies to most imported quartz. Slabs made in the U.S. are not affected, and imports from Canada, Israel, South Korea and several other countries are exempt. Slabs made in Spain, India, Vietnam, China or Turkey are covered. See the price section below.

• Silica content may decide what California shops can cut. On September 16, 2026, Cal/OSHA released a draft emergency rule that would ban manufacturing and fabricating artificial stone with more than 1% crystalline silica. As of October 3, 2026, it is a proposal, not law. See the silica section below.

What is the same across every quartz brand?

Engineered quartz (usually just called quartz) is made by mixing crushed quartz with a polymer resin, usually polyester, and pigments. The mix is pressed under vacuum and vibration, then cured with heat. The process was developed by the Italian company Breton in the 1970s and sold as Bretonstone. Most large producers run Breton lines or similar equipment. The slab that comes out is typically 90 to 93% quartz by weight and 7 to 10% resin. How it is made is covered in quartz countertops.

Because the recipe is shared, the everyday performance is shared too:

• Hardness. The quartz grains are 7 on the Mohs scale. Normal knife use will not scratch any brand.

• Stains. The resin fills the pores. No brand needs sealing, and a sales pitch for a quartz "sealing service" is a red flag.

• Heat. The resin is the weak point. Every brand warns that resin can discolor or crack at around 300°F (150°C), and a pan straight from a 450°F oven is enough. Every brand excludes heat damage from its warranty.

• Sunlight. Ultraviolet light slowly yellows or fades the resin. Standard quartz from every brand is for indoor use only.

So when a salesperson says one brand is "stronger" or "more stain-proof", ask for the spec sheet. Water absorption, flexural strength and hardness figures on the spec sheets of the major brands land close together.

What actually differs between brands?

Six things set the brands apart.

1. Design library and pattern realism. Premium brands put a lot of work into marble-look veining that runs through the slab body and does not repeat obviously. Budget slabs more often show a printed-looking vein that repeats every slab, which becomes visible on a long island or at a seam.

2. Consistency. A brand that runs its own production controls color from lot to lot (a lot is one production batch of a color). A brand that buys from several contract factories can see more variation in shade, pattern scale and thickness between batches.

3. Slab size. Jumbo slabs of about 130 x 65 inches let a fabricator cut a long island in one piece. Not every brand or color offers them.

4. Warranty. Terms range from 15 years to a transferable lifetime warranty, with different rules on registration and who must install it.

5. Distribution. Some brands sell only through approved fabricators. Others go through any stone distributor, company-owned centers or big-box stores. This decides where you can buy it and how much room there is to negotiate.

6. Silica content. Since 2023 some brands have moved to low-silica or near-silica-free formulas. This matters to the people who cut the slabs, not to the people who cook on them (see the silica section below).

The major brands at a glance

Prices below are typical installed prices for a standard kitchen with an eased edge and one undermount sink cutout. They are 2026 U.S. ranges, not quotes. Each brand's own entry colors overlap the next brand's premium colors.

Other names you will see on quotes: Daltile ONE Quartz (Mohawk's tile and stone arm), Wilsonart Quartz, Corian Quartz (the quartz line sold under the Corian name), Vicostone (Vietnam), Compac (Spain), Pental Quartz, Vadara, and regional distributor brands such as Arizona Tile's Della Terra and the quartz lines at Bedrosians. Most of these sit in the value to middle tiers.

Brand profiles

Cambria

Cambria was founded in 2000 by the Davis family in Minnesota and makes its slabs in Le Sueur, Minnesota. It is the best-known American-owned quartz brand made entirely in the U.S. It has the largest design library of the big brands, around 200 designs, and it is known for marble looks such as Brittanicca, Ella, Torquay, Swanbridge, Ironsbridge and Skara Brae.

Cambria sells only through its own network of approved dealers and fabricators. A shop has to apply, meet volume and quality standards, train with Cambria and display its samples. That is why you will not find Cambria at Home Depot or Lowe's. For the homeowner, this means a shorter list of places to buy and firm pricing. For the fabricator, it means less local price competition on the same design and little room to negotiate slab cost.

Cambria prices its designs in groups (tiers). Entry designs cost about the same as mid-range Silestone or Caesarstone. The top designs cost $40 or more per square foot above that, installed. Many designs come in a jumbo slab of about 132 x 65.5 inches. The warranty is a transferable full lifetime warranty, valid only when a Cambria-approved fabricator does the fabrication and installation.

Caesarstone

Caesarstone was founded in 1987 at Kibbutz Sdot Yam in Israel and was one of the first companies to sell quartz countertops worldwide. It has been listed on Nasdaq since 2012. Its business has changed in the last few years. It closed its Richmond Hill, Georgia plant, and in December 2025 it stopped production at its last Israeli quartz plant at Bar-Lev. Its quartz is now made entirely by third-party production partners to Caesarstone's specifications. Older articles that describe Caesarstone as "made in Israel and Georgia" are out of date. In August 2026 the company said it was evaluating how the new U.S. quartz safeguard tariff affects its production network.

Caesarstone uses open distribution. Any stone distributor can carry it, and it shows up at many fabricators. Colors carry four-digit codes (Calacatta Nuvo is 5131). The line is split into collections by price, from simple solid colors up to its marble-look designs. Standard slabs are about 120 x 56.5 inches, with jumbo slabs of about 131 x 65 inches on selected colors. In some markets it also offers 1.3cm material for walls. It sells an outdoor-rated collection with a UV-stable formula (priced higher than indoor colors) and ICON, a recycled-glass-based surface marketed as crystalline-silica-free, with up to 1% crystalline silica. As of October 2026, Caesarstone lists 12 ICON designs for sale in the U.S., in 2cm and 3cm jumbo slabs.

The residential warranty is lifetime for the registered owner. It can be transferred only if the first owner registered it, and the new owner gets a prorated 10-year limited warranty, not a new lifetime warranty. Register at installation.

Silestone (Cosentino)

Silestone belongs to Cosentino, a family-owned Spanish company founded in 1979 in Almería. Cosentino also makes Dekton, a sintered surface (see sintered stone), and Sensa, a factory-treated granite. Silestone is made in Spain and shipped to the U.S.

Cosentino runs its own distribution through Cosentino Centers, company-owned warehouses and showrooms in major U.S. metros. Fabricators open an account directly with Cosentino. Some Silestone colors also appear in big-box countertop programs in some markets.

Since 2023 every Silestone color has been made with Cosentino's HybriQ+ formula, which replaces part of the quartz with recycled glass and other minerals. Cosentino says all Silestone now contains 40% or less crystalline silica. Colors sold as Silestone XM, about a third of the range including all new collections, contain at most 10%. Cosentino also markets N-Boost, a surface treatment it says improves color depth and stain repellency, and it has promoted antimicrobial or bacteriostatic protection on some lines. Those hygiene claims come from Cosentino's own testing, and on a nonporous surface that is cleaned normally the practical benefit is hard to show.

Collections include Eternal (marble looks such as Eternal Calacatta Gold), Loft (concrete looks) and Sunlit Days (warm, matte colors). Finishes include polished, suede (matte) and volcano (textured). The warranty is 25 years and transferable. Standard slabs are about 120 x 55 inches and jumbo slabs about 128 x 63 inches.

MSI (Q Premium Natural Quartz)

MSI is one of the largest importers of stone and surfaces in North America. It does not own quartz factories. It buys from contract factories in several countries and sells under its own brand through dozens of U.S. distribution centers, to fabricators and through retail programs including Home Depot. Its quartz line is Q Premium Natural Quartz, often shortened to MSI Q, with a very large color range including popular marble looks such as Calacatta Laza and Calacatta Classique.

MSI's strength is price and availability. Its weakness follows from multi-factory sourcing. Shade, pattern and thickness can vary more between lots than with a brand that runs its own plant, and fabricators report occasional slabs that are slightly smaller than nominal or not perfectly flat. The fix is simple: buy the whole job from one lot, check the slabs on arrival and write the lot number into the job file. The warranty is a limited lifetime residential warranty for the original purchaser, and it must be registered within 30 days of installation.

HanStone and Viatera

These two Korean-owned brands compete in the middle tier with good marble looks at lower prices than the big three.

HanStone is made by Hyundai L&C, the company formerly called Hanwha L&C. Its North American slabs come from a plant in London, Ontario, which has produced quartz since 2009. In the U.S. it offers a lifetime limited residential warranty for the original owner. In Canada the warranty is 10 years. Terms differ by country, so read the document for the market you are in.

Viatera is made by LX Hausys, which was called LG Hausys until LG Group's 2021 restructuring. Only the parent name changed. The product, the Adairsville, Georgia plant and older warranties carried on. Many Viatera colors come in slabs of about 126 x 63 inches. The warranty is 15 years.

Store brands and private labels

A private label is a brand owned by a retailer or distributor rather than by the company that makes the slab. Allen + Roth is Lowe's house brand. Home Depot, IKEA and Costco each run countertop programs that combine a limited color range with subcontracted local fabricators. Regional distributors such as Arizona Tile (Della Terra) and Bedrosians sell their own quartz lines too.

Most private-label quartz is made by contract factories in Asia and performs like any other 90%+ quartz slab. The trade-offs are a smaller color range, more variation between lots, and warranties that are shorter or backed by a distributor rather than a manufacturer. A warranty is only as good as the company behind it. An independent fabricator usually cannot buy a retailer's private-label slab through normal channels, so the retailer's program is the only way to get it.

Why do quartz brands cost different amounts?

The slab is typically 30 to 45% of an installed quartz job. The rest is templating, fabrication, edges, cutouts, installation and the shop's overhead and margin. So a big difference in slab price turns into a smaller difference in the final quote.

Slab costs above are fabricator-reported and move with volume, distributor and promotions.

Within one brand, the price climbs with pattern complexity. Solid whites, grays and blacks are cheapest. Calacatta and Statuario marble looks with bold veins cost 20 to 40% more, because they are harder to make and waste more material when the veins must line up across seams.

A worked example: a 45 sq ft L-shaped kitchen quoted at three price points.

The edge upgrades, cutouts and tear-out cost the same whichever brand you choose. That is why a quote for a cheap brand and a quote for a premium brand often end up closer than the headline prices suggest.

Two other forces move brand prices. Import brands are exposed to trade duties. The U.S. put antidumping and countervailing duties on quartz surface products from China in 2019 and from India and Turkey in 2020, and renewed all of them in 2025 for another five years. Broader tariffs since 2025 have changed landed costs again. Since August 15, 2026, imported engineered quartz carries a four-year U.S. safeguard tariff: an extra 25% within a quota (counted quarterly) and 50% above it, on top of other duties, stepping down to 19% and 47% by the fourth year. Quartz from Canada, Mexico, Israel, South Korea, Australia, several other free-trade partners and many smaller developing countries is exempt, and natural stone is not covered. U.S.-made brands such as Cambria and Viatera avoid it, and so do HanStone's North American slabs, which are made in Canada. Silestone (made in Spain) and most quartz from China, India, Vietnam and Turkey are covered. Import-brand prices therefore swing more than domestic ones. Local competition matters too. The same slab can be quoted 20 to 35% apart by two shops in one city, which often outweighs the brand difference. How to compare full quotes is covered in cost by material.

Slab sizes by brand, and why fabricators care

Slab size decides how many seams a job needs. A seam is the joint where two pieces of stone meet. The table lists typical formats. Sizes vary by color, so confirm with the distributor.

Take an island top 128 inches long and 42 inches deep. It fits on a 131- or 132-inch jumbo slab in one piece. It will not fit on a 120-inch standard slab, so you need a seam or a jumbo in the same color. If the color you love comes only in standard size, ask about seam placement before you sign.

Weight matters for handling. At a density of about 2.4 to 2.5 g/cm³, 3cm quartz weighs about 15 to 16 lb per square foot and 2cm about 10 to 11 lb. A 3cm jumbo slab of about 60 sq ft weighs roughly 900 to 950 lb, and a 3cm standard slab about 700 lb. Slab dimensions and weights for all materials are in slab sizes and weights.

For fabricators, the practical rule is to nest to the slab you actually received, not the catalog size. Budget imports in particular can come in half an inch to an inch short, or slightly thin, and a layout drawn to nominal size can fail on the saw. See slab selection and inspection.

How do quartz warranties compare?

A quartz warranty is a manufacturer's warranty on the material. It covers manufacturing defects: cracking that is not caused by impact or bad support, delamination, or a color that clearly does not match the approved sample. It is separate from the fabricator's workmanship warranty, which covers seams, support, cutouts and level. A manufacturer will not pay for a bad seam, and a fabricator will not pay for a material defect.

Almost every quartz warranty excludes the same things:

• heat damage and thermal shock

• impact chips and cracks

• chemical damage from oven cleaner, paint stripper, strong bleach or high-pH cleaners

• outdoor use and UV discoloration (except outdoor-rated lines)

• damage from improper fabrication or installation

• normal wear

The differences are in the fine print. Read these four points in any warranty document:

1. Length. 15 years, 25 years or lifetime. Most real defects show up in the first year or two, so length matters less than it looks.

2. Transfer. Cambria and Silestone transfer to the next owner. Caesarstone gives a new owner a prorated 10-year warranty. MSI Q and HanStone (U.S.) cover the original owner only. Transfer matters if you may sell the house.

3. Registration. Many brands require registration within about 30 days of installation, with proof of purchase. Miss it and coverage can be lost.

4. Who must install it. Cambria requires an approved fabricator. Most others require professional fabrication and installation, and a DIY install usually voids the warranty.

Claims usually start with the fabricator, who inspects the problem and submits photos to the manufacturer. Approved claims normally cover replacement material. Labor coverage varies. More on claims is in warranties and claims.

Silica content: the newest difference between brands

Crystalline silica is the mineral form of quartz. When workers cut, grind or polish stone, it becomes a fine dust that causes silicosis, an incurable lung disease. Traditional engineered quartz is over 90% crystalline silica, far more than granite, and fabricators working with it have developed severe, early silicosis. The finished countertop in a home is not a silica hazard. The risk is in the fabrication shop and in any on-site cutting or grinding.

Regulation has tightened:

• In the U.S., OSHA's respirable crystalline silica standard sets a permissible exposure limit of 50 µg/m³ as an 8-hour average and an action level of 25 µg/m³. Fabrication shops fall under the general industry standard (29 CFR 1910.1053) and on-site work under the construction standard (29 CFR 1926.1153).

• Australia banned the manufacture, supply and installation of engineered stone benchtops, panels and slabs from July 1, 2024. The legal definition covers engineered stone with 1% or more crystalline silica, so today's "low-silica" quartz lines are still banned there; resin-free porcelain and sintered stone are not covered.

• California has had engineered-stone-specific rules under Cal/OSHA since late 2023, made permanent in 2025. The STOP Act (SB 20), in force since January 1, 2026, bans dry methods for high-exposure tasks on artificial stone and requires worker training, with a yearly attestation to Cal/OSHA from July 1, 2026. On September 16, 2026, Cal/OSHA released a draft emergency rule that would ban manufacturing and fabricating artificial stone with more than 1% crystalline silica. Comments closed September 30, 2026, and as of October 3, 2026, no Standards Board vote had been scheduled (it is not on the October 15 agenda). If adopted, the ban could take effect around December 2026 or January 2027. Check Cal/OSHA for the current status before relying on any date.

Brands have responded in different ways. Silestone's HybriQ+ formula (all colors 40% or less crystalline silica, Silestone XM colors 10% or less) and Caesarstone's ICON (marketed as silica-free, with up to 1% crystalline silica) are the best-known examples. Of these, only ICON-type products at or below 1% would stay outside California's draft ban. Traditional lines from most brands are still over 90%. Lower silica reduces risk but does not remove the need for wet cutting, dust extraction and respiratory protection, and "low silica" is a marketing term. Ask for the percentage on the safety data sheet. The health and compliance details are in silica and silicosis.

For homeowners: how to choose a quartz brand

1. Pick the look first. Shortlist two or three colors across brands. The same "white with gray veins" look exists at every price tier.

2. See full slabs. A 4-inch sample chip cannot show how the veins run across a slab. Look at the actual slabs, or at least a full slab of the same color, and ask to see two slabs from the same lot side by side if you need more than one.

3. Check the size against your layout. If you have a long island, ask whether the color comes in a jumbo slab and where the seams will go.

4. Read the warranty. Note the length, whether it transfers, the registration deadline and who must install it. Ask the fabricator for their separate workmanship warranty in writing.

5. Get itemized quotes from two or three shops. Compare material, fabrication, edges, cutouts and installation line by line. Make sure the exact brand, color name or code, and thickness are written on the quote, so a different slab cannot be substituted later.

6. Buy all the material you need at once. Brands retire colors. If you are remodeling in phases, a color may be gone by the time you do the bathroom.

If you are choosing between quartz and a natural stone, see granite vs quartz.

For fabricators: which brands to carry

Most shops stock or regularly quote two to four quartz brands: typically one value line for builders and budget jobs, one or two mid or premium lines customers ask for by name, and sometimes a closed-network brand such as Cambria. Weigh these points:

• Buying terms. A closed network (Cambria) protects your price but comes with volume commitments, audits and fixed slab cost. Company-owned centers (Cosentino) give you direct pricing, training and quick local stock. Open-distribution brands let you shop between distributors.

• Consistency and flatness. Brands with tight thickness tolerance make CNC programming and install leveling easier. With multi-source brands, receive every slab against a checklist: measure it, check flatness with a straightedge, look for pits and color shifts, and record the lot.

• Support. Color-matched seam adhesive guides, fabrication guidelines and a quick claims process save you money. Some value brands leave you to mix your own seam colors.

• Remnant value. Remnants of well-known brands resell more easily for vanities and laundry tops.

• Warranty compliance. If the brand requires an approved fabricator or registration, build it into your closeout paperwork and give the homeowner the registration link at install.

• Silica. Low-silica lines lower your exposure risk. In California, if the draft emergency rule is adopted, only products at or below 1% crystalline silica could legally be cut. Your wet cutting, dust controls and exposure monitoring still apply. See OSHA silica compliance.

Keep price lists by brand and price group current. Brands reprice several times a year, and import prices move with tariffs. A price list that is six months old can wipe out the margin on a premium job. Buying arrangements are covered in purchasing and suppliers.

Common mistakes

• Paying for a brand name to get durability. Hardness and stain resistance are about the same across brands. Pay extra for the look, the consistency or the warranty, not for performance.

• Mixing lots on one job. Two slabs of the same color from different batches can differ in shade. Pull the whole job from one lot.

• Assuming the warranty transfers. Only some do. If you are selling the house, check before you promise a buyer a lifetime warranty.

• Skipping registration. A 30-day registration window is common.

• Confusing quartz with quartzite. Quartzite is a natural stone with different care needs. See quartz vs quartzite.

• Nesting to catalog dimensions. Measure the slab you received before you cut.

Where software helps

Brand pricing is where quoting errors hide. Each brand has several price groups, colors move between groups, and slab costs change several times a year. In Stonify, each slab color is a catalog product with SKUs for thickness and finish, and price groups and pricing tiers hold retail, contractor and designer prices. Cost-based pricing recalculates selling prices when a supplier's slab cost changes. Slabs are received on purchase orders and tracked by lot and barcode, so a multi-slab job can be allocated from one lot and the lot number stays with the job for any later warranty claim. Customer catalogs limit a builder account to the brands and colors in its program.

FAQ

Is Cambria worth the extra cost? You pay for Cambria's design library, consistent slabs, American manufacturing and a transferable lifetime warranty. You do not get a harder or more heat-resistant surface. If a design you love is only made by Cambria, or you want the transferable warranty, it can be worth it. If a similar look exists in a mid-tier brand, you will not notice a difference in daily use.

Is Silestone or Caesarstone better? They are close in price and quality. Silestone has lower-silica formulas across its line and a 25-year transferable warranty. Caesarstone has a lifetime warranty for the registered owner and an outdoor-rated collection. Choose on the specific color and slab size.

Is MSI quartz good quality? It performs like any other quartz, and its limited lifetime residential warranty is competitive. Expect more variation between lots than with brands that run their own factories, so see the slabs and keep a job to one lot.

Which quartz brands can go outdoors? Standard quartz from every brand is indoor only. Caesarstone sells an outdoor-rated collection with a UV-stable formula. For most outdoor kitchens, sintered stone, porcelain or granite is the safer choice. See outdoor countertops.

Can I buy a brand's quartz slab myself and bring it to a fabricator? Many brands only sell to trade accounts. Some fabricators refuse customer-supplied slabs or charge extra, because they cannot warrant material they did not buy and inspect. Closed-network brands such as Cambria must be bought and installed through an approved dealer for the warranty to apply.

Do quartz brands discontinue colors? Yes, regularly. A retired color cannot be matched later for a repair or an extra piece. If you might add a vanity or extend a counter, buy the material now.
