Precious Metals...Platinum, Rhodium, Palladium, Gold....properties

There are more precious metals used in Jewellery than Silver and
Gold, precious meaning expensive. They are mainly Platinum, Palladium
and Rhodium. I include the others just for the sake of completeness.
This is a short guide to these metals, giving you an idea of some their
properties, relative relationships and uses.
All these metals have many industrial uses, some vital, and not just decorative.
As most of you are familiar with gold, I will use gold as a standard that describes their relative properties.
The values stated will vary somewhat with supply and demand
fluctuations, sometimes extremely, but it should give you a RELATIVE
idea in relation to gold. You can always get a current price on the net
if needs be.
