Got it.
Can you get olivine in australia?
Yes, it is quite common as most basalt (lava flows), and their eroded deposits will have olivine, although finding gem quality stones of a decent size is alway a challenge.
I have picked up a few in the Oberon and Nundle districts myself by taking a close look at basalt outcrops imbedded in basalt as single enveloped crystals or in geode like clusters. The single crystals have been larger in my specimens but extracting them is an issue as I have been splitting the basalt and shattering the stones, unless they were cracked in the cooling process.
I have a few rocks put aside that I would like to run through a saw at some stage to see if I can extract some decent stones.
