Gold and diamond are the most famous of all precious metals, widely sought after throughout the world for both its investment qualities and industrial properties. Gold has traditionally served three functions: as a monetary instrument, a financial asset, and a raw material mostly used in jewelry and decorative objects.
Diamond
Diamond has remarkable optical characteristics. Because of its extremely rigid lattice, it can be contaminated by very few types of impurities, such as boron and nitrogen. Combined with wide transparency, this results in the clear, colorless appearance of most natural diamond.
