A fully restored mammoth tusk

[Lhpanther]

Thanks for sharing. I’d love to have a fully restored mammoth tusk! How cool would that be!

I am under the impression that Schreger lines angles vary depending on their location, so if you only have a little bit of them visible they cannot tell all the truth. If you compare whole sections then they can be read and distinguished.

I'm not so sure about this, I have measured the angles of Schreger lines in hundreds of pieces and found them to be dependable. I am sure someone can come up with some ivory that is less concrete though.

Thanks again Doug.

These two are sold, I will post others in the "For Sale" forum when they are ready.

Thank you Mark, you are the expert! I bet you could tell it even with your eyes closed, just by smell

In this link you can check what i'm talking about. While the complete section is easily identifyiable as elephant, if you only have a small section of the inner part you can find more acute chevrons there and have some doubts.
It is possible i am still looking at it the wrong way and that even with small pieces there would be a way to tell for sure elephant from white mammoth interior.
