Treen & Treenware Collectibles
Also known as Tree of Life, this is the most dense wood in the world. It is filled with resins and is still used extensively. An Ebay search for this term may very well turn up old treenware items which are not listed under treenware.
A search of Ebay for Lignum vitae will also turn up some confusion about what is what. The original wood, the one used in the authentic old treenware pieces is from the tree species of the Genus Guaiacum. These are small, slow growing trees, so the supply has always been very limited.
You will also find sellers of "Lignum vitae" from Argentina where the species is Bulnesia sarmientoi. There is nothing wrong with having choices, as long as you know what you are paying for.
