Pros & cons of investing in gold vs. platinum?
@Michael Kjörling answered why platinum is in demand like it is.  But it missed some of the significant risks so I will address some of them.  Platinum is much more rare than gold.  But not because there is less platinum than gold just that the known existing platinum veins are smaller and more disbursed.  So if a large vein were found it could have a significant impact on the availability and thus reducing price of platinum.  New mining technologies are being developed every day.  One of these could make exacting platinum from existing not platinum mines easier and more cost effective again increasing the availability and reducing the price of platinum. The vast majority of platinum use today is for emissions controls.  There is a lot of money being thrown into research on green energy and technologies.  One of these technologies or a side effect of other research could result in much more cost effective ways to combat emissions.  Should that happen I would expect the price of platinum to fall through the floor and potentially never recover. I do not think any of these scenarios are imminent. But the risks that they present are so great it is important to consider them before investing.
