[QUOTE="user 4386, post: 343019, member: 4386"] Almost certainly not - I am unaware of any platinum minerals in quartz veins in Australia although it is known overseas and not impossible (South Africa). There are geological reasons for this. Natural platinum itself is quite soft, under 4 (unlike synthetic alloys) and extremely malleable - unfortunately some of the other platinum metals (eg iridium) can occur naturally alloyed with it, and can make it harder. Natural osmiridium, the most widespread platinum group mineral, is 6 - 7. I have never seen natural platinum-gold alloy - perhaps it can occur but I suspect it would be as rare as hen's teeth. Platinum minerals are extremely easy to identify - just get a pure enough piece out of the quartz and determine its SG. [/QUOTE]
