$5.00

Description

On an October early afternoon in 1960, a bright daytime fireball was witnessed by railway workers in a remote area of the Wiluna district of Australia. Many stones fell across a wide area and eventually some were recovered and analyzed. The distinctive glossy black stones are a type of eucrite achondrite that originates from the asteroid 4 Vesta. Millbillillie has a pale mottled matrix of grey and white that is metal poor.
