    Hi guys...

    New here... but hoping for a simple answer to a lingering question. I'm a huge fan of tanzanite stones... and I've collected a lot of jewelry pieces. Some violet blue, some blue violet, some totally purple... and one, very much blue. But is this possible? Perhaps I'm missing some sort of glimmer of violet/purple somewhere in the stone? Has anyone ever seen or heard of completely blue tanzanite with no violet/purple visible?

    Thanks for your help :)

    I’m no expert, but my understanding is that it’s a trichroic gemstone, so you should be seeing 3 colours.

    Do you have a photo?

    Must be affected by the direction it's cut.

    New Era Gems often offers Tanzanite in uncommon colors, including versions of blue.
    I would guess that most blues are the other axis color of the famous purple-blue-violet variety, but there certainly are other possibilities.

    Aren't most Tanzanites a yellow beige before they're heat treated? So, variations are bound to happen, as with any colored stones.
