These stones are linked with Cleopatra, and the emerald mine which bears
her name, located in Egypt near the Red Sea, was rediscovered in 1818. It contains
hundreds of shafts running into the hillside, some going down as deep as eight hundred
feet. Ancient tools found on the site enabled the mine to be dated to 1650 BC or
earlier. This mine was worked over a very long period and was the only known source
of emerald in the Ancient World. It can be assumed that all the rather poor emeralds
found in early jewellery came from it; those found on the site after its rediscovery were
not very prepossessing, being rather pale and cloudy. Another early source of
emeralds was a mine 7,500 feet up in the Austrian Alps near Salzburg: The Romans are
believed to have discovered this mine and again most of the stones now found in it are
pale and full of inclusions.
It was not until Pizarro conquered Peru in the sixteenth century and sent
back emeralds recovered by the Columbian Indians in the Andes that people in the western
world first appreciated how beautiful an emerald could be.
