Black Granite

Black granite can be sourced with a huge range of differences in grain and hue. The white grains are crystals of the mineral feldspar (the most common on Earth) and the black color comes from the minerals biotite and/or black mica. The ‘glassiness’ comes from the quartz in the granite. Stop by the yard to see the current black granite stone we have in stock.
