The jade used for the axe was sourced from Italy, not Britain.

Evidence

But there are actually sources of jade in continental Europe and, only a few years ago, in 2003 – some 6,000 years after our axe head was made – the precise origin of the stone it was made from was discovered. This luxury object is in fact Italian. — Neil MacGregor, A History of the World in 100 Objects, 251
