Platinum nugget
A nugget of platinum, a dense, malleable, ductile, precious, gray-white transition metal. It is one of the rarest elements in the Earth's crust. It exhibits a remarkable resistance to corrosion, even at high temperatures, and as such is considered a noble metal. As a result, platinum is often found chemically uncombined as a native metal.Photo: Alchemist-hp
