Platinum in terms of rarity surpasses gold by almost 90% in annual production. A placer platinum nugget in hard metallic form (the majority of placer platinum is a sponge of platinum and chromite) is almost incalculable in rarity. Crystalline form is the absolute rarest precious metal on Earth.... see more ›
Can Platinum be attracted to a magnet? In its purest form, Platinum is a paramagnetic metal. This means that its magnetic element is so weak that it is barely traceable and will not react to magnets. However, pure platinum is considered a precious metal and is one of the rarest materials on earth.... read more ›
