Every detail in natural stone comes from the perfect mix of minerals, creating colors, veins, and textures that can’t really be copied. It’s a natural formation that holds the story of the Earth, shaped over millions of years.
A very common mineral in the continental crust made of pure silica. It is essential in granites, sandstones, and quartzites and is known for its high hardness and glassy shine. It is highly resistant to weathering and forms beach sand. It comes in many colorful varieties, like amethyst, and is important for making glass and watches.
A group of phyllosilicates known for their green color, from the Greek “chloros.” It is typical of low-grade metamorphic rocks like greenschist. It forms from the alteration of minerals rich in iron and magnesium. It looks like mica and flakes apart, but its layers are not elastic and won’t return to their original shape after being bent.
An important group of dark inosilicate minerals. They are rich in calcium, magnesium, iron, and silica and are dominant in igneous rocks like basalt and gabbro. Their short, prismatic crystals, usually black, form a large part of the Earth’s mantle and volcanic lavas and are also common in many meteorites.
