Platinum group minerals (PGMs) are among my favorites – Physically and chemically tough species, resistant to acid attack, capable of surviving many miles of very rough travel down raging creeks. Did you know that if, god forbid, your house should burn down, the native platinum group nuggets in your collection will be among the only half dozen or so mineral species that survive to be sifted intact from the ashes? All your other minerals will either melt, burn, crack or crumble to dust. And did I mention RARE? Forget native gold – common as dirt, relatively speaking – I can find traces of mere gold in almost every river, all over the world. But the platinum group minerals (platinum, iridium, osmium, ruthenium, palladium, rhodium and their alloys) are really much harder to find than gold. And as for those mystical fools who believe in the healing energy of quartz and other crystals... Forget it; platinum is the only mineral with true mystical powers – Owning a handful of PGM nuggets magically turns even a wimpy geek like me into a macho man.
