This is because tanzanite is abundent (usually gems are a comodity because the supply is restricted for some reason or other making them rare, i.e. see http://cecileraleydesigns.blogspot.sg/2016/06/what-makes-rare-gems-rare.html?m=1).
Furthermore tanzanite is very soft and damages extremely quickly, this will effect the resale vlaue of preloved items, see

If you would like to buy a piece of tanzanite for the joy of wearing it. Then paraibainternational has a large inventory, there is a beautiful high end ring on jewels by grace at the moment (sorry typing phone otherwise i would find the link for you). But as an investiment stone it may not be your best choice.
