Check out this one: Is it spinel or D-block tanzanite?![]()

Hmmm. I did not think about all that black in the stone.
Frankly, I don''t know why some people compare Iolite with Tanzanite either!
I''ve been checking around on ebay, and all of the Iolites there look ''dead'' with no color or sparkle like tanzie. Someplace I had read that Iolite was a ''sleeper,'' the Tanzie replacement-to-be. And no, it was not on JTV.![]()

The extreme reaction of iolite to a dichroscope gives it away too. No other blue/purplish stone I''m aware of throws dark purple, light blue and colorless so distinctly with this instrument. Heck, the blue to colorless phenomena can be seen with no tools in good light.
