Quartzite has similar if not stronger physical-mechanical features than granite. Quartzite is suitable for both internal and external applications depending on the particular type. Quartzite 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.




A unique work of art can be seen in Mother Nature's semi-precious stones. Semi-precious Stone slabs incorporate a dazzling 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. Care must be taken not to subject the semi-precious stone to intense heat, or any place where there is a sudden change in temperature. Recommended for internal use only. 
These desirable stones are limited in availability and due to high cost are exclusively “import on order” products. 


Marble is a metamorphic rock resulting from the metamorphism of limestone formed under immense heat and pressure. The mainly calcite composition is recognised by its characteristic swirls and veins deriving from various mineral impurities originally present as grains or layers in the limestone. Of mid-range hardness (approx. MOHS 3–4), marble is ideally suited for bathroom tops, walls and flooring. Marbles uniqueness makes it desirable for kitchen tops, but care and maintenance needs to be a consideration when choosing this stone. 

Marble is traditionally used internally in a high polished, mirror like finish however is now also appreciated externally in a variety of finishes such as honed, brushed and sandblasted with a vast range of colours and patterns available.


Granite is an igneous rock formed from magma deep within the earth's crust, granite is generally composed of quartz and feldspar providing high range hardness. In recent years discoveries of so called 'New Granites' have introduced vibrant and amazing opportunities in colours and patterns, no longer limiting the range in granite to only homogeneous patterns.

Extremely scratch resistant, heat resistant and chip resistant with low porosity makes granite an excellent material for both internal and external applications. Ideally suited for kitchen bench tops and flooring, granite's resistance to all types of weather is also the perfect solution for external cladding. Traditionally finished in a high polish, new technology has produced a recent trend towards textured finishes such as flamed, brushed and leather finishes.


Onyx is a calcareous material with a very fine grain and many veins running concentrically to one another, the presentation of the stone is largely dependant on its directional cut. This translucent stone is synonymous with luxury living, a widely recognised presence in the homes of the rich and famous, Onyx is often back-lit to add brilliance and extra dimension. Of mid-range hardness, produced in a high polish finish Onyx exposes an eclectic array of colours and patterns of distinct beauty.

Travertine is quarried from ancient hot mineral springs in exotic lands, Travertine is a banded, more compact form of Limestone, characterised by the many holes and chambers evident through the stone. 

Travertine varies in colour from dusty white to silver-grey, to gold, coral red and toffee, available filled, unfilled, honed or polished creating a classy and sophisticated appearance. 

Current trends have moved towards a honed finish opting for a more untouched "old world" like appeal. Travertine is suitable for both internal and external applications.

Quartz (Engineered Stone)

  • Engineered stone, also known as quartz, is practically maintenance-free. This kind of stone does not require any sealing, and it is resistant to stains, acid, scratches, and heat. Available in many colors and patterns, quartz has become a very popular countertop option in the 21st century.
