Zero Crystalline Silica vs. Ultra-Low Silica

Zero Crystalline Silica

These listings carry a seller-published Zero Crystalline Silica claim. Confirm the current manufacturer technical documentation before fabrication.

Nouvel Ultra-Low Crystalline Silica

Bedrosians markets Nouvel as an ultra-low crystalline silica engineered quartz surface. Its June 2025 SDS lists total crystalline silica at 3% or less by weight, with composition varying by color. Nouvel is not presented here as a zero-silica claim.

California's Proposed 1% Artificial-Stone Rule

California is considering an emergency rule that would prohibit the fabrication and manufacture of artificial stone containing more than 1% crystalline silica. The September 16, 2026 Cal/OSHA document is a discussion draft, not a final rule. Because some products marketed as ultra-low silica can still be above 1%, buyers and fabricators should check the current rule status and the exact product SDS before fabrication.

Silica-Free & Low-Silica Quartz Terminology

Buyers often search for silica-free quartz countertops, zero-silica countertops, or low-silica quartz. The Stone Index groups these products inside Quartz inventory and treats silica content as a separate product-specific attribute.

A Quartz label does not establish one universal silica percentage. Confirm the exact zero- or ultra-low-crystalline-silica claim with current manufacturer documentation.

Silica-Free Quartz Countertops FAQ

What does silica-free mean for countertop surfaces?
On this page, silica-free refers to products specifically marketed with a zero-crystalline-silica claim. Buyers and fabricators should still verify the current manufacturer technical and safety documentation before fabrication.
Is ultra-low silica the same as zero crystalline silica?
No. Zero crystalline silica and ultra-low crystalline silica are different claims. Bedrosians currently markets Nouvel as an ultra-low crystalline silica engineered quartz surface, and its June 2025 SDS lists total crystalline silica at 3% or less by weight.
Is every quartz slab silica-free?
No. Quartz is the buyer-facing material category on The Stone Index, while silica content is a separate product attribute. This page includes only listings with an identified zero- or ultra-low-crystalline-silica claim.
Is Macaubas Bookmatch on this page natural quartzite?
No. The Macaubas Bookmatch listing shown here is a manufactured Bedrosians Nouvel quartz surface, not natural Macaubas quartzite.
Does a zero- or ultra-low-silica claim remove normal fabrication safety requirements?
No. Fabricators should follow the current manufacturer SDS, wet-cutting and dust-control guidance, required protective equipment and applicable Cal/OSHA rules for the exact product.
What if a listing says “Quantity to confirm”?
That means the seller has an active product listing but the current piece count has not been verified. Contact the seller directly for current slab availability before planning a project.
