CORNISH GRANITE
  
Unpolished sample

De Lank Quarry, 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. The crystals of mica sparkle in reflected light. It is presented in a lidded gift box.
