Mammoth ivory / fossil mammoth tusk is a material very dense so it takes detail well.
Mammoth tusk also has a specific grain, which is quite beautiful and differentiates it from other illegal ivory sources.
The colour variation is endless, depending on what minerals was next to the tusk in the ground.
Our material comes from Siberia (researchers have found mammoth fossils dating from up to 30,000 years ago in Russia).
