Well said / typed. Thank you!qubitasaurus|1471156488|4065777 said:I think that the point the above posters are trying to make is that you will be lucky to recoup what you paid when you resell. 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.
