Lavrion is one of the most mineralogically diverse mining districts on Earth, where silver, lead, and copper were mined as far back as antiquity. Over the centuries, the oxidized zones of these ancient ore deposits have produced an enormous variety of secondary minerals, including this copper smithsonite.
While pure smithsonite, that is, zinc carbonate, is actually colorless or grayish-white, this piece owes its attractive coloration to fine traces of divalent copper in the crystal lattice. This cupro variety displays the delicate mignonette green to subtle mint green so typical of the region. The botryoidal growth pattern is particularly well-developed. The crystals form dense, rounded aggregates with a waxy to matte luster, giving the specimen its characteristic, almost velvety appearance, reminiscent of famous mines like Hilarion or Kamareza.
The showpiece is further enhanced by the aesthetic contrast with the brown, iron-rich limonite matrix. This matrix perfectly accentuates the green of the mineral and makes the specimen a classic, historically valuable addition to any discerning collection of European minerals.
