welcome to the forum, Mike.
what part of the world are you in ??
there is "real" Lignum Vitae - and there is the "other kind".
what country did the wood come from ???
to be sure of what you have, you need to take a sample to someone that
really knows the stuff.
I myself would like to have a few of the pieces that will fit in a Flat Rate USPS box.
providing the price is where it should be.
right now, it is a "sight unseen" product. for all we know, your friend could have
brought home some mango wood - we have no way of knowing for sure.
please do the best research you can of exactly what you have - then the you can price it.
another source is the Wooden Boat
forum - they use a lot of Lignum in boat building.
and there are many discussions there about the "real" Lignum and the "looks like" Lignum.
of course, PHOTOS would be most helpful.
I buy most of my turning stock off of E-Bay. but, the speciality exotics I get from Bell Forest Products
their wood is certified to be Grade-A Hand Select with no to minor defects.
also, the wood is certified to come from a reliable and sustainable source.
if the wood you have has any kind of defects, splits, cracks, bugs, etc, the price
would of course be much, much less than Bell Forest.
looking forward to your follow up.
