In comparison to other alloys/metals, platinum occurs in much smaller quantities and as a resource is considered extremely rare. Due to this, it naturally valued more highly and is often perceived as the "premium" of whatever the subject.
In jewelry, designers often choose platinum settings to communicate an elite status for their piece. It has a natural resistance to tarnishing and corrosion. It is harder than pure iron and yet very ductile, meaning it can be manipulated into designs better than other metals.
