Engineered quartz has been one of the most popular countertop materials in America for years. Lately, it has also been in the news. California regulators are considering restrictions on fabricating high-silica engineered stone, and Australia banned the material outright in 2024. If you are planning a kitchen or bathroom project in Florida, you may be wondering what this means for you.

Here is a clear, homeowner-focused look at what is happening, what it does and does not mean for your home, and how natural stone fits into the picture.

Why engineered stone is in the news

The concern is about workers, not homeowners. Engineered quartz is made mostly of crushed quartz bound with resin, and many products contain more than 90% crystalline silica. When slabs are cut, ground or polished, they can release very fine respirable silica dust. Long-term exposure to that dust can cause silicosis, a serious and incurable lung disease. Public health researchers in the United States have documented cases among stone fabrication workers, particularly in shops that cut without adequate water suppression or ventilation.

What regulators have done so far

• Australia banned the use, supply and manufacture of engineered stone benchtops starting July 1, 2024.
• California: in May 2026, the state’s Occupational Safety and Health Standards Board voted to direct Cal/OSHA to begin rulemaking that could prohibit fabricating and installing artificial stone containing more than 1% crystalline silica. An advisory committee met during the summer and early fall of 2026, and the proposal is still being developed. No ban is in effect yet.
• Federal level: OSHA’s respirable crystalline silica standard already limits how much dust workers can be exposed to and requires controls such as wet cutting and ventilation. It applies to all stone fabrication, natural or engineered.

As of this writing, there is no ban on engineered stone in Florida.

Is my existing quartz countertop dangerous?

No. An installed countertop that is not being cut or ground does not release silica dust during normal use. Cooking, cleaning and everyday wear do not create a meaningful exposure. The risk sits in fabrication shops, where slabs are cut and shaped.

If you ever need to modify an existing counter, for example cutting a new sink or cooktop opening, hire a professional fabricator who uses wet-cutting methods and dust controls.

Does natural stone contain silica too?

Yes, and it is worth being honest about this. Granite, quartzite and other natural stones also contain crystalline silica, and fabricating any stone safely requires the same kind of dust controls. Quartzite in particular is very high in quartz. The main difference is that many engineered quartz products are consistently above 90% silica, and researchers have also raised questions about the resins and how the material breaks down during cutting.

The takeaway: no countertop material is “silica-free” to fabricate. What protects workers is responsible fabrication. That is why it pays to work with established, professional fabricators.

Why more homeowners are choosing natural stone

Regulation aside, many of our customers are moving toward natural stone for reasons that have more to do with design and performance:

• Character: every natural slab is one of a kind, with real veining and depth. Our guide to how veining forms explains why.
• Sun and heat resistance: granite and quartzite do not contain resin, so they handle Florida sun and hot cookware better than engineered quartz.
• Outdoor use: natural stone is the go-to for lanais and outdoor kitchens.
• Longevity: a well-maintained granite or quartzite countertop can last for decades.

Natural stone alternatives to engineered quartz

If you like quartz because it is low-maintenance

Granite is your closest match. Many granites are dense and need sealing only occasionally, and darker, patterned granites are very forgiving with everyday spills.

If you like quartz because it looks like marble

Quartzite offers the white, veined look many people buy quartz for, with natural depth and excellent hardness. Stones like Cristallo quartzite are standouts. For an even softer, more classic look, consider dolomite; compare the two in our dolomite vs. marble guide.

If you like quartz because it is consistent

Natural stone will never be perfectly uniform, but you can get close by choosing stones with subtle, even patterns and by selecting all your slabs from the same block. Our guide on why two slabs of the same stone can look different explains how to plan for that.

Questions to ask your fabricator

• Do you cut and polish using wet methods and dust collection?
• Does your shop follow OSHA’s silica standard?
• Can I see and approve my actual slabs before fabrication?
• How will you plan the layout and seams to match the veining?

Frequently asked questions

Is engineered quartz banned in Florida?

No. As of October 2026, there is no ban on engineered stone in Florida. California is considering restrictions on fabrication of high-silica engineered stone, but no rule has been adopted there either.

Is it safe to keep my quartz countertops?

Yes. The health risk comes from dust created when slabs are cut or ground, not from using an installed countertop.

Is natural stone a safer choice?

For homeowners, both are safe once installed. For workers, natural stone also contains silica and requires the same safe fabrication practices, though it typically contains less silica than most engineered quartz.
