Considering the excavation of mammoth ivory in Canada, Siberia and the Arctic regions, prehistoric mammoth ivory along with fossil ivory is one of the limited resources that connect mankind to the ancient eras. A piece of history preserved by time, best describes mammoth tusk ivory. Sometimes the tusks are unearthed during gold mining while other fossil ivory tusks have been found while archeologists were sifting through ancient Eskimo villages. Most of the tusks have been preserved well in permafrost, ash and soil.
Buried during the last ice age, wooly mammoths perished and became an extinct species while the carcasses that are dug up are prized for huge tusks that sell for high prices. Most of the mammoth ivory that is recovered from the permafrost has lay buried for over 11,000-12,000 years and is generally termed as fossil ivory even though the organic material is still soft to carve.
The colored bark of the ivory is due to the minerals in the soil and ice permeating into the ivory. Some of these are calcite, iron, quartz, silica and pyrite which start the process of recrystallization. Although these darkish brown old tusks look old, they are prized world over due to the quantity of legal ivory each has. These are prized and rare commodities that ivory carvers and collectors demand but even then the constant supply falls short as investment in mammoth ivory is lucrative as it is a limited resource.
