Description

    BLUE SMITHSONITE
    Lavrion District Mines, Attikí Prefecture, Greece Lavrion (Laurium), Greece, is 60 kilometers southwest of Athens and its mining history dates to sometime around the 11th Century BCE. The Silver mines located there produced the Silver coinage that powered the Athenian navy and the Greek state - and continued to do so up until the early 20th century when mining ceased. Initially miners were after the Lead/Silver ores and later operations broadened their activities to include production of Manganese, Cadmium and Zinc. It is this later period of operation that was responsible for this lustrous, sea blue-green slice, with the delicately banded layers. It was sliced from a group of stalactites composed of Smithsonite, the carbonate of Zinc, surrounding a 'Limonite/Goethite' core. Small traces of Copper give the Smithsonite the pleasing pastel hue that is unusual in this mineral. It is translucent, except for the orange material forming the original core of the stalactite group, and has been polished on both sides to a brilliant luster. Not just a lovely mineral specimen, this attractive bit of lapidary work represents a slice of history from a critical location in the development of Mediterranean culture. Overall measurements are 3 7/8 x 1 3/4 x 1/4 inch (9.8 x 4.4 x .6 cm), and it is in fine condition.


    Estimate: $2,400 - $2,800.
