Few interesting facts about platinum

I thought a few facts about platinum might be good to introduce here because many of them were new to me prior to beginning my search for my wife's engagement ring.

First off, platinum is extremely pure - much more so

 than other precious metals.  At 90-95% purity, platinum is hypoallergenic, which means if your skin is at all sensitive, platinum is one of the few metals out there that wont cause an allergic reaction.

Platinum also has a ton of uses aside from the obvious (jewelry).. uses include:

Catalytic converters, fuel cells, gas refineries, glass fibre, flat panel screens, pacemakers, computer hard disks, personal razors, tableware, chemotherapy drugs and radiation treatment.

I found some of this info at PreciousPlatinum.com
