A Quick Comparison of Bluestone and Granite

06 March 2020

A wide variety of stones normally plays a huge role in construction and landscaping works. They serve as the principal material for the foundation of infrastructures. These stones are also used for the construction of walls, arches, dams, and many more. In landscaping, stones help organise and define the aesthetic elements of a backyard or garden.

Two of the most common stones that are used in construction and landscaping are bluestone and granite. These two stones are frequently seen in large buildings and landscaping elements. They give off different properties that can be useful for some specific applications.


Bluestone is the blue crystalline form of copper sulphate commonly found and used in Australia. It underwent millions of years of compression from geological pressure and heat just to form its solid layers.

Granite, on the other hand, is a common type of light-coloured igneous rock that can come in colour white, pink, or gray. It was formed due to the slow crystallisation of magma below Earth’s surface. It is composed mainly of quartz and feldspar with a minor amount of mica and other minerals.


Bluestone is a type of fine-grained sandstone that is commonly known as arkosic sandstone. This type of stone shifts and appears in colour blue when it is broken or wet. In some cases, however, bluestone can come in other colour options. This type of bluestone is known as feldspathic sandstone.

As mentioned, granite is an igneous rock that is composed of feldspar, quartz, and other dark minerals. This specific mineral composition gives the stone a red, pink, gray, or white colour. Aside from the general colour, some dark mineral grains are also visible throughout the rock.


Bluestone is fairly durable and can resist cracking. One of the best qualities of bluestone is that it can be separated and processed into slabs of any desired size. It can also be honed, sanded, rubbed, or treat thermally to create great appearance and texture. However, bluestone must be cleaned more often than granite because of its high porosity.

Alternatively, granite is the most durable of all the building stones. It has a high load-bearing capacity that can be useful in construction and landscaping works. It can even resist weathering and can be cut and shaped without flaws. Both the crushing and abrasive strength of granite is also high.


Bluestone is widely used in bridges, driveways, walls, steps, landings, indoor projects, outdoor paving areas, patios, and many more. It can also be used in pool copings, countertops, tables, fireplaces, and architectural facings.

Granite can also be used in a lot of construction and landscaping projects. Rough-cut and polished granite is frequently used in large building projects for structural stones, wall cladding, roofing, and exterior decorating. Polished granite slabs can also be used in countertops, tile floors, stair treads, and other decorative features.

If you are looking for a stone for your construction or landscaping projects, both the bluestone and the granite can deliver the best possible outcome that you can get. If you want to know more about these stones, you can ask us anything at AM Stone Masons.
