What is KönigZero?
Königstone has launched KönigZero, a collection of 28 zero-crystalline silica* engineered stone surfaces that deliver the durability, resilience and timeless aesthetic of traditional Quartz without the associated hazards explained below. It represents the evolution of engineered stone, offering homeowners a safe, future-proof alternative to traditional Quartz, without compromising on performance – or design.

What are the benefits?
• A safer choice – Crystalline silica-free engineered stone removes the concernsthat have surrounded Quartz in recent years, giving customers peace of mind.
• No compromise on quality – KönigZero performs like Quartz: durable,scratch-resistant, consistent in colour and suitable for all kitchen and bathroom applications.
• A full palette of 28 colours – From classic neutrals to contemporary tones, therange supports every kitchen design.
• Accessible pricing – KönigZero is positioned to be a mainstream option, not apremium or niche material.
• Backed by a trusted UK brand – Königstone has been supplying premiumsurfaces since 2005 and is known for reliability, service and design leadership.
Why does Zero matter?
The safety of Quartz worktops has been under scrutiny following cases of silicosis among stonemasons exposed to Respirable Crystalline Silica (RCS) during fabrication. While responsible fabricators have long implemented strict controls, the industry has been seeking materials that reduce risk at source.
KönigZero directly addresses this need. By replacing Quartz, which is high in Crystalline silica, with natural minerals, KönigZero eliminates the primary cause of concern while maintaining the performance standards expected by UK kitchen retailers and homeowners.
What testing has been undertaken?
The team at Königstone has spent three years developing and testing zero silica engineered stone, both in controlled environments and in real world fabrication settings. More than 700 KönigZero worktops have already been fabricated and installed, allowing the material to be assessed for:
• Technical performance (strength, durability, stability)
• Fabrication behaviour (cutting, polishing, finishing)
• Dust generation and safety impact in a live production environment
*May contain trace levels, below 1%, of crystalline silica.
