Pleochroism

[ps_bond]

Possibly a daft question - does anyone know if CZs can exhibit pleochroism?

I wouldn't have thought so - (this is just guesswork though) isn't one of the things about CZs that they are almost too pure?

I should read more carefully...

Isometric minerals cannot exhibit pleochroism

Cubic zirconia is crystallographically isometric, an important attribute of a would-be diamond simulant.

So basically, there's no dopant can get them to show pleochroism cos then they wouldn't have the cubic structure.
