Platina er mer verdifullt enn gull, fordi det er mer sjeldent, og prosessen fra et platina funn til ferdig barre tar ca. 5 mnd, mens gull tar ca. 4 - 5 uker. Ringer av platina inneholder 95% platina sammenliknet med 14karat gull, som inneholder 58,5%. Den samme ringen veier 50% mer i platina. Vi sier at platina er ca. tre ganger så dyrt som. Platinum metal has a number of useful properties, which explains its application in a wide range of industries. It is one of the densest metal elements—almost twice as dense as lead—and very stable, giving the metal excellent corrosion resistant properties
