Tarnish-resistant silver?
Quote this post and reply to it Post#1 @ 03-17-09 , 02:32 PM


I was wondering, what exactly goes into tarnish-resistant silver? i.e. 'sterlite'. I first learned about sterlite when I was at a refinery a few weeks ago and saw it on a list of precious metals on a chart. I was told Tiffany & Co. had created it years ago, but the copyright expired sometime in the 1980s and other people are now creating it. Tiffanys still uses it, too. The silver purity is .925, the same as regular sterling, but that remaining alloy is what prevents it from tarnishing. Anybody know what it is? Is there a story to it?

Thanks,
Ryan Thompson G.G.

I hadn't thought that Tiffany's was involved. The only sterling one which I've heard of is called "Argentium" and it uses a bit of germanium in the alloy. Here's a link to a Wikipedia article: Argentium article

There are a couple of good links at the bottom of the page there as well.

I had also heard of someone who was marketing a platinum/silver alloy which had excellent qualities as well.

I'd heard about 'argentium' but I thought it was a different product from 'sterlite'. Looking for sterlite on wikipedia turns up a metal mining company based out of India. Silver isn't mentioned, though.

Would you happen to know what (or approximately) percentage of germanium is used? Thanks

I have no idea. You might go to their site and sign up. They may have more information deep in the bowels of their site.
