      Help me Indentify this metal     

Ok not sure if this is the right place to post(hope so). I've been searching the net all over trying to figure out what this metal is that i have.

Usually i dissolve gold plated metals in nitric acid to dissolve whatever base metal is underneath so i can retrieve the gold flakes that stay solid in the solution,
 then dissolve the gold in aqua-regia for later refining. but i've come across a metal that WILL dissolve in aqua-regia, but not in nitric acid alone. when left to soak in the nitric acid it will turn pink..

Anyway i'm hoping someone will remember a metal that will not dissolve in nitric acid and then turns pink.. but will dissolve in aqua-regia.

Thanks for any help
