I read the reason for tungsten is the weight among other reasons it is supposed to be the easiest way to disguise it.
Alloy it with some osmium and it would have the same density as Gold, Plate it with gold and perfect duplicate.....
Some histories I’ve read indicate that in the 1700’s some counterfeiters plated a newly discovered grayish metal with gold and sucessfully passed it off as the real thing. That metal is now called ‘platinum’. ;~)
