Or, more likely, Palladium.  Other possibilities include: silver, platinum,
chromium, cobalt, tin, zinc, and indium.

I found this weblink quite useful:

Possible use of Tungsten in jewellery gets a brief mention at:

  http://en.wikipedia.org/wiki/Tungsten

"Tungsten is also beginning to see uses in jewelry. Its hardness makes
it ideal for rings that will never scratch, and will in turn not need
polishing (this is especially good for brushed designs)."

Google is your friend.  :)

Hope it helps.

Cheers,
Paul.
