- Platinum is the hardest of the precious metals. It never tarnishes. Its intense luster remains intact over the years and it is completely hypoallergenic. The name originates from the Spanish word platina meaning ‘little silver’. Platinum is the rarest of the precious metals.
- Platinum is closely related to five other metals, Palladium, Ruthenium, Rhodium, Osmium, and Iridium. Together these six metals are know as the Platinum group metals or PGMs.
- Platinum’s supply / demand fundamentals are tight. In fact, if platinum mining were to cease today, above ground reserves would last less than one year. In contrast, gold reserves would last nearly one quarter of a century. In contrast with Gold and Silver, there are no large above-ground platinum stockpiles to fill the gap against significant disruptions.
