Quartz is an engineered stone. Unlike Granite, Quartz is man-made, by combining 97% Crushed Quartz and 3% Resin. This makes the stone just as strong as granite, but slightly heavier. Currently it is the most popular material being used for kitchen tops. A main advantage of quartz kitchen tops is that they are low maintenance. The engineered stone is non-porous, meaning that the material doesn’t stain and doesn’t require a sealer, unlike Granite, Quartzite & Marble.
Granite is a light-coloured igneous rock. It forms from the slow crystallization of magma below Earth’s surface. Granite usually has grains that are large enough to be seen by the unaided eye. Granite is composed of minerals – mainly quartz and feldspar. Its mineral composition is what usually gives granite its red, pink, grey or white colour with dark mineral grains visible throughout the rock.
Quartzite is a naturally occurring metamorphic rock. It is created when sandstone is subjected to extreme heat and pressure caused by tectonic plate compression in the crust of the earth. The stone is mined and sawn into slabs which are later precisely cut to become countertops. Kitchen tops made of quartzite are polished and sealed for beauty and durability.
Onyx is cryptocrystalline, and incorporates numerous minerals (including quartz) in a layered pattern of combined, alternating bands. Though stunning, onyx is fragile–the fragility of the stone makes it more difficult to remove from the earth, which is part of the reason it’s more expensive, as well as the fact that the conditions needed to create onyx are much rarer than other stones. There are few natural stones in the world with the same kind of power to impress as onyx. Onyx is beautiful, rare, and the ultimate luxury item for high-end kitchens and homes.
