California is considering a ban on producing quartz countertops because cutting and fabricating silica-containing slabs can expose workers to hazardous dust. Good Housekeeping says its lab tested silica-free surfaces and other countertop materials, reporting strong performance in its tests; the proposed ban has not yet taken effect.
California is considering a ban on quartz countertop production because fabrication can release crystalline silica dust linked to silicosis, while Good Housekeeping reports that its lab tests found several silica-free and non-quartz alternatives that performed well. The proposed ban has not taken effect and still requires a vote, according to the magazine’s report.
Quartz countertops are made from engineered material whose main ingredient includes crystalline silica. The risk described in the report is tied to fabrication and installation: cutting slabs can release fine particles into the air if workers are not using protective practices. The report says wet cutting and adequate ventilation can help reduce exposure. Once a countertop is installed in a home, it says, the silica-dust concern no longer applies to ordinary use.
Good Housekeeping’s Home Improvement & Outdoor Lab says it tested silica-free quartz surfaces from Neolith and Caesarstone. The report says experts reviewed independent testing of Neolith’s formulation and checked third-party safety and environmental certifications, including Greenguard and International Organization for Standardization certifications. In the lab’s evaluations, Neolith resisted stains, heat and scratches; the magazine still recommends using cutting boards and trivets.
Caesarstone’s ICON surface, introduced in 2025, also performed well in the magazine’s tests for stain, scratch and heat resistance. The report lists other options, including porcelain and natural stone. Caesarstone porcelain performed strongly against stains in the tests and, according to the report, can be used outdoors because it resists ultraviolet exposure and temperature extremes.
How Fabrication Risk Affects Remodels
The proposal could affect countertop manufacturers, fabricators and people planning kitchen renovations, particularly if restrictions change which products can be made or sold in California. The health issue highlighted in the report is primarily an occupational exposure risk: workers may inhale silica dust while slabs are cut, rather than homeowners being exposed to dust from an intact, installed countertop.
For consumers, the test results offer possible substitutes but do not settle which material is best for a particular project. Performance, appearance, maintenance needs and price differ. Natural stone, for example, can offer distinctive patterns, but the report says porous marble needs more attentive care. People comparing products should also distinguish a silica-free engineered surface from conventional quartz, and ask installers how they control dust during fabrication.

Silica Dust and Countertop Choices
Engineered quartz has become a popular countertop choice in the United States over the past two decades, according to Good Housekeeping, in part because of its design range, durability and relatively easy maintenance. The material’s silica content becomes a concern when manufacturing or installation work generates airborne dust.
The report describes silicosis as a chronic, incurable lung disease that can develop when inhaled silica particles lodge in the lungs and cause scarring. It does not say that installed quartz countertops pose the same risk during routine household use. Alternatives mentioned include porcelain, granite, marble and quartzite. Although quartzite has a similar-sounding name, the report identifies it as natural metamorphic rock, not engineered quartz.
Good Housekeeping gives a price range of $50 to $130 per square foot for natural stone, describing it as comparable to premium quartz. The report does not provide a full price comparison across all the tested alternatives.
“The lab reported that its tested silica-free quartz alternatives “aced” its performance tests.”

The Proposal and Its Scope
The source report does not identify the proposed measure’s bill number, sponsors, exact wording, timetable or the date of a vote. It therefore remains unclear which production activities or products would be covered, what requirements could apply to fabricators, and whether the measure would include exceptions or a phase-in period. The report also does not establish whether the proposal would restrict sales or installation, as distinct from production.
The performance findings are Good Housekeeping’s test results. The supplied report does not give detailed protocols or results for every product, nor does it compare the long-term cost and maintenance of all alternatives. The reported certifications and product characteristics should not be read as proof that every countertop option is risk-free under every handling or installation condition.
A Vote Before Any Ban
The immediate milestone is a vote on the proposed California measure, which the report says is still needed before it can take effect. No vote date or implementation schedule is provided in the source material. Until the proposal’s status and terms are confirmed, homeowners and contractors should not treat a production ban as already in force.
Consumers planning renovations can compare silica-free engineered surfaces, porcelain and natural stone with suppliers and installers, while asking how slabs are cut and how dust exposure is controlled. Further reporting would be needed to confirm the proposal’s final language, the outcome of any vote and any rules that follow.
Key Questions
Has California banned quartz countertops?
No. The report says a proposed production ban still needs a vote before it can take effect. It does not provide a vote date.
Why is quartz countertop production a health concern?
Quartz contains crystalline silica. Cutting or fabricating slabs can release airborne dust that workers may inhale; the report says this exposure can cause silicosis, a chronic and incurable lung disease.
Are installed quartz countertops described as a silica-dust risk?
Good Housekeeping says the concern described is dust released during fabrication and installation, and that an installed countertop does not present the same silica-dust concern during ordinary home use.
What alternatives performed well in Good Housekeeping’s tests?
The report says its lab found strong performance from silica-free surfaces by Neolith and Caesarstone ICON, and also reports good stain resistance for Caesarstone porcelain. Results apply to the products and tests described, not necessarily every product in those categories.
What does natural stone cost, according to the report?
Good Housekeeping lists natural stone at about $50 to $130 per square foot, a range it describes as comparable to premium quartz. The figure is not a full price comparison of all countertop materials.
