    ARAGONITE / CALCITE

    Aragonite/Calcite
    Laurion District Mines, Laurion District, Attikí Prefecture, Greece

    Were it not for the mines of Laurion, Athenian Greece would never have been the naval power that defeated the Persians at the battle of Salamis in 480 BCE, setting the stage for the "Golden Age of Athens." The rich Silver deposits of Laurion were first worked before 600 BCE, and it was the discovery of a new vein in the mine that supplied the money necessary to build and outfit the 200 triremes that achieved that victory. Silver is but one of the metals mined at Laurion and the complex chemistry of the deposit has resulted in 476 valid minerals being recorded as coming from the district. One of the "showier" of Laurion mineral specimens is this Copper-infused Aragonite/Calcite group displaying "Robin's Egg Blue" color, fading to white on one side. It is a very big plate with hundreds of "frost-like" translucent growths emerging from a matrix of massive Calcite, Azurite, and Malachite. The line between Calcite and Aragonite is not easily determined visually, since the composition of either mineral is the same: the term tends to be used interchangeably. Luster is an odd mix of glassy and waxy, partially due to the small size of some of the crystal faces. It is in excellent condition, with only a couple of 'dings' around the edges; it is surprisingly free of damage for such a significant museum-sized specimen. It comes with a custom stand.
    Overall Measurements: 10.7 x 9.1 x 3.7 inches (27.1 x 23.0 x 9.3 cm)
    Offered at no reserve.


    Estimate: $7,000 - $10,000.
