Doe v. Artificial Stone Defendants
A countertop fabricator who developed fatal silicosis from exposure to dust from crystalline silica artificial stone secured $27 million in settlements from artificial stone manufacturers and suppliers, in one of the first civil cases to highlight a growing public health crisis caused by a uniquely toxic product.
In a growing epidemic, thousands of countertop fabricators in the U.S. who worked with crystalline silica artificial stone slabs have been sickened with fatal silicosis lung disease from the nano-sized silica and other toxic particles the slab product releases when fabricated into kitchen and bathroom countertops and installed. Most of the affected workers are low wage, immigrant, and Spanish-speaking-only laborers who are among the most vulnerable and marginalized in our workforce. The vast majority of workers do not learn of the risks of working with artificial stone until after they receive diagnoses of silicosis, which leads to progressive suffocation, oxygen dependence, lung transplantation, and death. The case nominated as a finalist—Doe v. Artificial Stone Defendants—is at the vanguard of hundreds of lawsuits filed by Brayton Purcell LLP to seek redress for these workers and hold the industry accountable.
John Doe, now 51 years old and dependent on supplemental oxygen, spent many years cutting, grinding, and polishing crystalline silica artificial stone slabs—products composed of at least 90% crystalline silica, with the remaining portion made up of highly toxic metals and resins that release volatile organic compounds (VOCs) during fabrication. His job as a fabricator exposed him to extraordinarily fine, nano-sized silica particles that penetrate deep into the lungs. These particles differ dramatically from the much larger silica particles present in natural stone and are far more toxic. Mr. Doe’s dedication to supporting his family through this career came at a steep price: accelerated silicosis with pulmonary massive fibrosis, a terminal disease caused by the nano-sized crystalline silica particles released during routine fabrication. His lawsuit was filed in December 2022. He alleged that artificial stone manufacturers designed, marketed, and distributed a product inherently unsafe to fabricate by human beings, and that they did so despite decades of peer-reviewed scientific studies documenting the unique toxicity of respirable crystalline silica dust produced during the fabrication of artificial stone slabs. He further alleged that warnings accompanying the slabs were inadequate, failing to disclose that even the most rigid adherence to wet cutting, ventilation, and respirators cannot prevent workers from inhaling dangerously high concentrations of respirable crystalline silica.
The case involved contending with 43 defendants, propounding 107 discovery requests, responding to 197 discovery requests, responding to 23 non dispositive motions, taking or defending 76 depositions, defeating 12 motions for summary judgment, filing 23 motions in limine, opposing 56 motions in limine, and serving 152 page lines for deposition and/or discovery designations to be used at trial. As part of the firm’s investigative efforts, the team identified more than 50 former coworkers with relevant knowledge and carried out extensive outreach to locate, contact, and interview the potential witnesses.
During jury selection in April 2025, the defendants agreed to pay more than $27 million to Mr. Doe and his family. This settlement represents one of the most significant recoveries in the United States for artificial stone–induced disease and reflects the
catastrophic harm caused by fabricating crystalline silica artificial stone. It also underscores the reality confronting countless fabrication workers: the very act of showing up to work each day to cut and polish these slabs exposes them to uniquely toxic, nano-sized crystalline silica dust that no respirator, ventilation system, or wet cutting methods can eliminate.
In fact, there is no safe way for human workers to fabricate crystalline silica artificial stone, even when shops follow all OSHA prescribed controls. In California alone, confirmed crystalline silica artificial stone silicosis cases surged from 13 in 2019 to 567 cases by early June 2026, including 31 deaths and 58 lung transplants (with 51 additional victims referred for lung transplantation). Many of those diagnosed are in their 30s and 40s—ages at which they should be supporting families, not fighting for survival. Artificial stone silicosis is a global epidemic, with documented outbreaks in Israel, Spain, China, India, the UK, and Australia. Australia banned crystalline silica artificial stone in 2024 after concluding it cannot be fabricated safely by human beings. Public health agencies in the U.S. are finally beginning to respond, designating the disease as reportable and issuing urgent advisories to clinicians and fabrication communities. In May 2026, the Cal/OSHA Standards Board unanimously voted to implement an Emergency Temporary Standard to prohibit the fabrication of artificial stone containing more than 1% crystalline silica.
It is litigation like this that will ensure corporate accountability and force this dangerous product from the market.
