CORNISH GRANITE

Bodmin Moor, Cornwall

Cornish granite varies in texture but is usually speckled with white feldspar crystals, translucent quartz, and muscovite and biotite mica. It has been widely used as a building stone in Cornwall and as a decorative stone worldwide.

 

Granite now forms the backbone of Cornwall, part of the Cornubian batholith, created during the Variscan mountain building episode ​​​​​in the late Devonian and Carboniferous periods. 

 

This is a good sample with two cut edges so it displays well.  The crystals sparkle in reflected light.
