Ain't smokin nothing... Swear to God. MOST of the ivory being used to make grips today is Fossil Wooly Mammoth or mastadon ivory taken from tusks excavated from the frozen tundra of Siberia.
You may have seen press on the WHOLE Wooly Mammoth excavated this year in Siberia in a state of PERFECT preservation. One HUGE chunk of ice with 2 HUGE tusks sticking out of the front.
Much of this ivory can be as old as 25,000 years. Makes no difference...Cold has perfectly preserved it. If you DON'T believe me then find a gripmaker at gunshow and ask... they will confirm this.
