How is platinum usually found on Earth?
Platinum in the Earth’s crust originates from ultra-mafic igneous rocks. It can therefore be associated with rocks like chromite and olivine. In nature, pure platinum is unknown and well formed crystals are very rare. Platinum is typically found as nuggets and grains.

How is platinum used in the real world?
Although it was discovered relatively later by European scientists, it has been found in Egyptian tombs dating back to 1200 BC. It is also used in laboratories for electrodes.
