Are Australian sapphires really worth anything?

[QUOTE="user 1769, post: 174679, member: 1769"] Good resource, Lefty, I think this applies fairly widely. Down here sapphires have been found associated with basalt flows, mostly. But not always. And 'associated' does not mean 'coming from'. There are areas in NE Tas that have small basaltic pipes. Sapphires have been found surrounding those, but also in places where no basalt remains. Did it weatehr away? Perhaps. I think pyroclastics (ash) carried much of the sapphire, and not so much the basalt. [/QUOTE]
