With an age of between 10,000 and 15,000 years; the tusks of mammoth ivory come from the Siberian steppe, where the cold has kept its properties intact. The melting and erosion of permafrost are contributing to their release. Since the ban, a fortunate but insufficient measure, of trading in elephant ivory, the use of mammoth ivory has increased. The two types of ivory can be differentiated thanks to the drawings they present in the fangs (Schreger lines).
