Generally Marble can be seen as an advanced form of Limestone. Elements of heat and pressure upon Limestone causes it to metamorphose and form Marble. Comprised of Calcite or Dolomite crystals, Marble can be classed according to the amount of magnesium carbonate present.
The presence of impurities in Marble are responsible for variety of colour available. From grays and blacks to greens and reds, these colours appreciate and enhance the quality of the Marble.
For eras Marble has been a choice material for the construction of statues and monuments as well as facing and feature stone for many buildings worldwide.
Granite is a slightly more complex rock. Commonly Granite is believed to be have solidified from magma (molten rock), but it also appears that rock can also metamophose into Granite, meaning that, Granite is also metamorphic in some circumstances as opposed to being igneous (solidified from molten rock).
Granite can be comprised mainly of quartz and feldspars is usually course-grained and of even texture and light colour. The colour variation in Granite which can be pink, dark or light grey is due to the amount of feldspar in the rock.
Like Marble, Granite has also been using for centuries as a building material adding grace and character to where it is applied.
