[QUOTE="Heatho, post: 113289, member: 487"] Mate if it were Platinum it would be very heavy like Gold, actually Platinum is heavier. You could try a specific gravity test, if it is a Platinum Group Metal or an alloy of PGM's it will still be very heavy and very hard. PGM's take a high temperature to melt. Simple SG test. [url]http://johnbetts-fineminerals.com/jhbnyc/articles/specific_gravity.htm[/url] Platinum is found in Australia and so are a few other PGM's, it is quite rare though. There is an alluvial Platinum mine in NSW near Condobolin, also a few other deposits of PGM's in beach sand and with some Gold deposits. An example is Osmiridium in Tasmania in alluvial deposits.
