I. The Metaphysical Reading

How the stone has been held.

Lakelandite is worked with as a stone of home landscape, held by people from the Lake District or those who have found it a place of recovery. It is said to steady the carrier by reminding them of a specific horizon of hills.

II. The Scientific Reading

What the lattice actually does.

Lakelandite is a lapidary trade name for an ornamental welded tuff from the Borrowdale Volcanic Group of the English Lake District, an Ordovician sequence of andesitic to rhyolitic pyroclastic rocks laid down around 450 million years ago. The rock is a lithified pyroclastic flow deposit — feldspar and quartz crystals set in a fine ash matrix now recrystallised to chlorite and epidote — and the same regional geology built Cumbria's fell landscape. It takes a good polish and is used mostly in local jewellery.
