How Do You Get Different Coloured Granite? 

Different coloured granite is common, with granite worktops available in a huge range of hues and patterns. Nowadays, more and more homeowners are opting to have granite countertops installed on account of their quality and durability. If you have an interest in granite worktops and how the stone is formed, you may have wondered why so many granite colour options exist. Today, we are going to explore granite colour options in depth: asking how manufacturers obtain different coloured granite. 

Why Are There Different Granite Colour Options?  People often see the wide range of granite colour options available and believe this is altered in the manufacturing process. A lot of people are often surprised to find out that, as granite is naturally formed, different coloured granite is not altered. Conversely, the colour of granite is a process that occurs naturally.  To give you a bit of context, granite is an igneous rock that was formed deep underground. Granite is the result of magma or lava cooling and solidifying under intense pressure. The colour is produced as a result of the rocks' makeup as well as the mineral percentage. Common minerals found in granite include sodium feldspar, potassium feldspar, and amphibole. Quartz also makes up the majority of granites' genetic makeup, with 20-60% of the minerals in granite typically being quartz.  The formation of the granite and its mineral composition is, essentially, how we are awarded different granite colour options. Granite containing predominantly quartz, for example, will look hugely different to granite with a large potassium feldspar percentage. Below, we explain different coloured granite in relation to mineral composition.
