Description

Tiny gold specks on pseudomorphs of bismite after bismutite / bismuthinite, accompanied by blue-green sprays of mixite on earthy brown matrix. Surely good for further analysis of the mineral composition.

A very rare and hard to get locality specimen from ancient Lavrion mines. The area was mined since the egyptian age and most intensively from 600 B.C. to 100 A.D., for silver, lead and other metals. The Lavrion mines were the main source of wealth for the city of Athens during the classical times (5th-4th century B.C.). They were abandoned during the Roman times and reopened in 1865. All mining activity stopped in 1984.
