Android Launcher Icon for Gold price widget

BullionVault Price Widget

I have created an Android home screen widget to show the current gold or silver price in the BullionVault markets.

The application is very simple and designed to do this one job well.

People interested in the current gold or silver price in the BullionVault market.

I'm looking for a simple, clear icon that implies both gold and silver but, failing that, the suggestion of gold is preferable. It should also have some indication that a price is involved (though not through something like a dollar sign because multiple currencies are involved)

The Icon:
1. Must follow the standard Android Phone Icon design guidelines:

2. Must be delivered in the following sizes: 512x512, 72x72, 48x48, and 36x36. It should look reasonably good at all these sizes so avoid intricate detail that gets lost at the smaller sizes. Design for 48x48 and see that it scales up and down well.

I would prefer .SVG, but will accept .png at appropriate resolutions
