Using a loupe for Tanzanite?

[Molon Labe]

Hi,
I've read that Tanazanite should appear free of contaminants to the naked eye. At what level of magnification is it normal to see contaminating minerals in Tanzanite?
Sorry if this is a stupid question.

Thanks for your help.

As with any gem, if you can only see inclusions at 10x, it’s probably eye clean. However, once you start wearing a tanzanite, I recommend never looking it under a loupe or magnification again, because you’ll see so many facet abrasions and micro pits, it will drive you crazy. As a soft and brittle gem, that’s just a thing you have to contend with.
