Types of Granite

Hornblende Granite

• Hornblende granite is the darkest variety of granite. It is durable in all types of weather, making it ideal for almost any use.
  
  

Biotite Granite

• Biotite granite is available in a wide variety of colors and is one of the most widely used granites for building. It is the hardest of all granites and can be used indoors or outdoors without compromising the stone.
  
  

Talcose Granite

• Talcose granite is one of the lesser known forms of granite because it doesn't withstand elements well. That makes it less than ideal for flooring, countertop and outdoor use, which leaves only decorative purposes.
  
  

Tourmaline Granite

• Tourmaline granite is available in a wide range colors, with the exception of colorless and white, which are extremely rare. This type of granite is ideal for areas without a lot of traffic, as it is the softest of all types.
  
  

Color Classifications

• Some companies classify granite according to colors instead of by composition. Companies that classify in this manner boast over 100 types of granite. However, choosing a granite based on color alone is a recipe for disaster as the granite you choose may not be appropriate for the application.
