Zero Crystalline Silica vs. Ultra-Low Silica

Zero Crystalline Silica

These listings carry a seller-published zero-crystalline-silica claim. The Stone Index preserves that product-specific wording and recommends confirming current manufacturer technical documentation before fabrication.

Nouvel Ultra-Low Crystalline Silica

Bedrosians describes Nouvel as an Ultra-Low Crystalline Silica Mineral 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 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 Quartz Countertops & Mineral Surface Terminology

Buyers often search for silica-free quartz countertops, zero silica countertops or quartz alternatives. Manufacturers may instead use terms such as Zero Crystalline Silica, Ultra-Low Crystalline Silica or Mineral Surface. The Stone Index keeps the seller's material category while separating the silica claim from the material label.

“Mineral Surface” does not by itself mean silica-free. The exact crystalline silica level belongs to the individual product line and current technical documentation.

Silica-Free Quartz Countertops FAQ

What does silica-free mean for countertop surfaces?
On this page, silica-free is buyer-facing shorthand for products specifically marketed with a zero-crystalline-silica claim. The exact product documentation still controls, and buyers and fabricators should verify the current technical and safety data 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 describes Nouvel as an Ultra-Low Crystalline Silica Mineral Surface, and its June 2025 SDS lists total crystalline silica at 3% or less by weight.
Is every Mineral Surface silica-free?
No. Mineral Surface is a material category, not a silica-content guarantee. The Stone Index only includes products on this page when the current listing or product line has a specific zero- or ultra-low-crystalline-silica claim that we can identify.
Is Macaubas Bookmatch on this page natural quartzite?
No. The Macaubas Bookmatch listing shown here is Bedrosians Nouvel Macaubas Bookmatched Mineral 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.
