Silestone� (Made in Spain)
Made in Spain by Cosentino, it claims that this it's technology is over 15 years old, making it the old player in the field of quartz stone surfaces. The makers of Silestone promoted it as a classic or contemporary, inner-city chic or colonial charm in their product. Silestone is another brand if engineered stone which is technically similar to the other brands because it is comprised of approximately 93% quartz and 7% epoxy binders.
As with all other quartz stone surfaces, Silestone is scratch resistant, stain resistant, amd heat resistant. Silestone has a color range of over 40 Colors. Silestone claims to have received the best possible score for stain resistance from the CSIRO. It also has a 10 year limited warranty.
A unique feature is Silestone is the Microban technology that is intergraded on the product. Microban claims to continuously fights the growth of microbes that can cause stains and odors and Microban protection makes your Silestone countertops easier to clean and keeps them cleaner between cleanings. The promotion of Microban antimicrobial protection is that it is effective against most common bacteria, yeasts, molds and fungi that cause stains and odors. Microban technology is not designed to protect users from disease-causing microorganisms.

Zodiaq� (Made in Canada)
From the maker of Corian, comes Zodiaq�. DuPontTM Zodiaq� claims to have produced an advanced composite material made of 93% quartz with a DuPont proprietary binding polymer and pigments. If anyone has the money for R&D, DuPont does.
Their stated goal was to create a new material with its own depth and character and a unique aesthetic, suggesting a sense of enlightened luxury and an attitude of bold sophistication. Zodiaq� covers the gamut with alternative to the polished finish and a collection of matt finish colors in neutral tones. Just like the other quartz stone and otherwise known as engineered stone brands, Zodiaq� has a very sophisticated technology. When you think of Zodiaq�, most people do not know that it is made by one of the largest and most sophisticated countertop maker in the world.

Cambria� (Made in USA)
Perhaps the smallest player in the market is Cambria quartz stone surfaces which is American owned and operated by the Davis Family. This company has gone from manufacturing cheese for over 60 years to luxury quartz stone product and their website claims this is a natural fit. Regardless of their smaller marketing approach, Cambria does offer some unique colors that the other bigger brand do not. Their color choices are worth looking and the pricing is competitive with the other brands.
As with all the other brand names, Cambria quartz stone surfaces are also comprised of approximately 93% quartz and claim the same low maintenance advantages.

CaesarStone� (Made in Israel)
CaesarStone� it is made of approximately 93% quartz by weight. The other 7% is epoxy resin which is required to hold the quartz together. Quartz is one of the hardest minerals and is calculated at a hardness level of 7 on the Mohs Scale of Hardness.
CaesarStone� is manufactured in Israel. The company proclaims to be the originator of quartz kitchen and bath countertops, and claims to have advantages over other surfaces. Benefits include less chipping, cracking or discoloring and a less porous surface that does not require sealing. Many installation professionals dispute Caesarstone's claims that it does not allow bacteria growth and cleans with just a moist cloth. It is promoted to resist damage from heat and acids such as caustic wine spills and knife scratches. These claims are also questionable.
The colors that CaesarStone� offers are different than other brand names listed below and are perhaps more popular because of this characteristic. Honed finishes and marble-like textures are a couple features.
CaesarStone� offers a 10 year limited warranty, when installed by a Certified Fabricator. Read the limited warranty carefully as it is very 'limited'.
