Cornish Granite

Cornish Granite is Carboniferous to early Permian in age (around 290 million years old) and is still quarried in several locations, the most well known being De Lank Quarry, Bodmin Moor.

Cornish Granite has been used locally since Neolithic times for monuments, local housing and lighthouses. It has also been used across the UK e.g. the British Museum, Tower Bridge and more recently the Diana Memorial Fountain in Hyde Park, London. Cornish Granite varies in colour and texture depending on the source location. Colour varies from silver grey to honey brown, it is generally coarse grained with large biotite flakes and megacrysts of white orthoclase feldspar.
