I'm going to challenge you to prove that statement Spectre. It's absolute nonsense. There's only one source in the world for the blue zoisite known as Tanzanite: the Merelani Hills of Tanzania. There has been no civil war in TZ since Tiffany & Co. introduced the stone in the 1970s.
Thanks,
I feel better.
I do know they mines flooded and then petered out so to speak.
Disregarding a "civil war", there have been and are conflicts concerned with mining that stone..At least from what I've understood..
I.E, from a 2002 GEM article
"At Mererani, South African Gem (Afgem) is accused of human rights abuses and attempting to monopolise tanzanite mining.
Miners have been shot dead or chased by dogs. Afgem says it is defending its interests against trespassers. It certifies the tanzanire it sells to guarantee the gems' authenticity. Although Minerals and Energy Minister Maokola-Majogo has told Afgem to stop doing so, it continues the practise, claiming it is an effective market strategy."
