6 months after purchasing a sapphire from gemfrance.com that was sold as unheated, a friend that is a hobby gemmologist had a look at it and said he thought it was heated. Double checked with a gemological lab and it indeed it was heated. Laurent from gemfrance.com refused to except a return because the sale was done more then 6 months ago. Massively overpaid for the stone and wasted 250 Euro for the gem report! DO NOT BUY FROM THIS SCAMMER!
