8 types of natural stone
There are numerous types of natural stone, each with their own characteristics, so researching the sustainability of natural stone is important if you want to use it in your new home.
Basalts are one of the most common rock types in the world. They are usually grey to black in colour and are fine-grained. They are sometimes characterised by small holes in the stone structure and their grey tones and subtle patterns make it a very popular choice for both interior and exterior applications.
Granite is an igneous rock formed from magma deep within the earth's crust. Granite is generally composed of quartz and feldspar making it extremely scratch, heat and chip resistant. Its low porosity makes it an excellent material for both internal and external applications, mainly suited to kitchen benchtops and flooring.
Quartzite has similar, if not stronger, physical-mechanical features than granite. It is suitable for both internal and external applications depending on the particular type and can uniquely offer colours and veining similar to that of marble with the added benefit of the hardness of granite, making this the ideal kitchen bench top material.
Limestone is a sedimentary rock composed largely of calcite. Commonly Limestone is produced in a honed finish, as most are not able to take a high polish due to its delicate nature. Limestone is generally ivory, browns or greys in colour and has a low to mid-range hardness.
Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is soft and can be easily damaged, comprising primarily of calcite and often containing other minerals such as clay, micas, quartz, iron oxides and graphite.
Onyx is a calcareous material with a very fine grain and veins running alongside each other. It's a translucent stone synonymous with luxury living and often produced in a high polish finish to expose the colours and patterns.
Semi-precious stone slabs incorporate an impressive arrangement of hand selected Quartz, Amethyst, Petrified Wood and Fossils. Available in large format slabs, the 30mm thick slabs are resin backed making them suitable for further fabrication.
Travertine is a banded, more compact form of Limestone, characterised by the many holes and chambers through the stone. It varies in colour from dusty white to silver-grey, to gold, coral red and toffee.
