Fossil mammoth ivory from Siberia comes with a certificate of authenticity (with an estimated age of between 7,000 and 10,000 years). It occasionally contains brown or blue-green inclusions due to the presence of iron phosphate, vivianite (blue iron earth).
Collecting the rare material always involves making a field expedition. This means getting together solid teams of specialists and effective operational logistics for the Arctic environment. During the period of thaw, the prospectors dig into the permafrost close to rivers, searching for any traces of plant life that could flourish on an organic terrain. Once the zone has been marked out, they dig the ground and pull out any mammoth tusks and other fossil ivory found there. The next step is to cut the ivory up into wafer-shaped pieces that will be used to dress the knife.
Occasionally, North Sea fishermen find pieces of fossil ivory in their nets that have recently been released from the sediment. This material is slightly different from that found in Siberia as the enamel is the only useable part and it is strongly colored in the middle. The thin layer of healthy material is nevertheless sufficient to make handles for folding knives.
