Selo Pedreira Própria - Santo Antonio Stones

Granito Etna Black

Inspirado na magnitude do vulcão siciliano, o Granito Etna Black é uma manifestação de força geológica bruta. Sua composição exótica, rica em feldspatos e micas como biotita e muscovita, cria superfícies de beleza surpreendente e movimentada. O grande diferencial técnico desta rocha é sua capacidade de retroiluminação, que revela camadas translúcidas ocultas e transforma a pedra em uma obra de arte luminosa. Ideal para quem busca impacto visual dramático com a resistência de uma rocha natural apta para ambientes internos e externos.

SEE THE MINERALS

que fazem o Granito Etna Black

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.

MINERAL

Plagioclase

The most abundant mineral series in the Earth’s crust, part of the feldspar family. Their chemical composition includes sodium, calcium, aluminum, and silica. They are important for classifying igneous rocks and range from white to gray. They are commonly found in basalts and granites and usually show fine, typical striations on their crystal surfaces.

MINERAL

Quartz

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.

MINERAL

Biotite

Biotite – rich in iron, magnesium, and potassium. It is commonly found in igneous rocks like granites and in metamorphic rocks like gneisses. Its perfect cleavage allows the mineral to peel into thin, flexible, and elastic sheets. Its dark color and glassy shine are very typical visual traits in rocks from the Earth’s crust.
