Quartz is one of the most common minerals in the Earth's crust, naturally occurring in many types of stones, sand, and clay. In its solid form, quartz is harmless, but when materials containing quartz are processed – such as through cutting, grinding, or polishing – harmful quartz dust can be released. Inhalation of this dust is associated with serious diseases such as silicosis, COPD, and lung cancer, and handling such materials therefore requires extensive safety measures during production.

Natural Safety Without Quartz
Larvikite and Anorthosite, the two Norwegian natural stones that make up Lundhs’ stone portfolio, contain no quartz minerals. They consist mainly of feldspar and mafic minerals, and are therefore classified as quartz-free natural stones. This means that processing Larvikite and Anorthosite does not generate harmful quartz dust. The materials can be cut, ground, and polished without the need for specific measures related to quartz dust. This makes them a safe and responsible choice for architects, designers, and contractors who wish to use natural materials with documented health and safety assurance.

A Conscious Choice for Sustainable Projects
When selecting materials for construction and design projects, it is essential to consider technical and aesthetic qualities in addition to the working environment. While quartz composites often contain high levels of quartz, Larvikite and Anorthosite are natural and safe alternatives – without compromising on quality or technical performance.

With their unique appearance, durable surface, and local origin, Larvikite and Anorthosite represent a sustainable and health-conscious choice – both for those who work with the stone and for those who live with it.
