Why Do Two “Same Karat” Gold Rings Feel Different on Skin and Wear Differently?

Two gold rings marked 18K can contain exactly the same proportion of gold yet behave differently on the finger. One may look pinker, another whiter; one may develop scratches more visibly, while another may leave a dark mark on the…
