Mammoth ivory knife handle material

​
Mammoth ivory is popular for knife handles. Here I offer matched sets for use as knife handles. Prices vary due to grade of ivory, color, weight , size . Some will  be all natural, some stabilized, some stabilized and dyed. I try to distinguish  in the description. All natural can  be cost prohibitive! Unstable can fall apart! Some material needs filler in the back to make it flat, fill voids. Most material I find myself and originates here in Alaska and is about 40,000 years old. All is dry and been out of the ground over a year. I make knives myself so understand the fossil needs and can answer questions on suitability etc. 
What gives the colors to the fossils?
Ice-age material is 10 -80,000 years old. Over this time period several factors effect cold, but mostly it is minerals in the soil migrating in. Copper suspended in water gives blues as is turquoise- assurize malachite. Iron tends to offer up reds. Bacterial algae gives greens. Fungus can give purples. Damage to the fossil weak spots take on minerals faster. Temperature and sun effect color, and the fossil can move in an earthquake etc causing new exposure to different areas and thus a color mix within the same fossil. 
What does stabilized mean? 
Fossils are old, most often a weaker material then the original raw. There can be rot, cracks, serious bends. Such material is unsuited for use in projects. Stabilizing is a way ti fill cracks, impregnate resin, straighten, add desired colors so the fossil material is stronger, more water-resistant and less likely to expand contract or change over time.  Many desirable natural desired colors are rare, and expensive. Adding to color to the impregnating resin gives a natural or desired look without the exorbitant  price. Rocks like turquoise as well as most woods are 'altered' dyed stained stabilized and fossils are added to this list. All natural or stabilized will be marked and priced accordingly by ethical dealers as with anything from nature taht has been altered.
How is fossil ivory graded?
It is difficult! Not all dealers agree! I used to be a trapper. Fur dealers go by about 26 grades, but furs are bought from trappers- sold to the public in just 3 grades. The fossil market is similar. Solid good color good shape for specific markets like knife makers is easy to grades as high and desirable! Gooig down in grade are warps, inside or outside curves, internal material, cracks and soft spots. If some if this has blue the grade is still high. Material taht needs stabilizing to be dependable is lower grade. The bottom line will be, what will a customer pay and can a craft person turn it into a reasonable profit? You can ruin grade A, or turn grade C into a work of art! In general grade A takes less knowledge and ability to make look nice, the material speaks for itself. Power grades are usually 'a problem,' of one kind or other and a professional understands and can work with the crack the soft spot etc. Lower grades could have more character and treated correctly can be the most desired! This is part of what makes it hard to put a level of desire on it and corresponding price. Outer bark is enamel and tends to be harder so is usually higher grade. I have videos to watch to help choose a grade. 
How accurate are measurements-weight?
This is sold as 'raw material.' Each different and unique with minimal work put into it because shop time is $65 an hour and the question comes down to how much of my time do yo wish to pay for compared to how much is materials cost? My weight is most accurate as ivory tends to sell by the weight within a grade category. Thickness can vary by 1/16th so I round up or down or give an average. Measurement is n o more accurate than the width of the bad saw blade. I'm not going to recut it. See specific pieces for more money will have the comment on better accuracy, for those for who it matters a lot. if you have a project requiring exacting fit, square evens, drop me and note and I can tell you if a selected piece will work for your project. Keeping in mind the best flat and square will usually coat more.
