Here's a real life consequence of the absolute nonsense spouted by Gemporia these days (images from an active eBay listing - main photo & listing detail). Once upon a time, Gems TV sold blue kyanite as just that.
Mentioned lots of times on this forum, the constant proximate use of the words "nilamani" and "sapphire" by all Gemporia presenters when selling blue kyanite has made its mark on this eBay seller. I'm not suggesting that TGGC is responsible for the eBay listing but I am saying that they are responsible for the eBay Seller declaring the main stone as a sapphire, describing it as "sapphire" twice, with no mention of the word "kyanite" anywhere - even, of course, on the Gemporia certificate which is displayed in the listing.
