Precious stones

In the broader sense, rare natural stones sought after by buyers (diamonds and colored precious stones such as rubies, sapphires, and emeralds). – In the narrower sense, only diamonds. High-carat diamonds, also rare in form, both rough and polished, are estimated to be held worldwide for investment purposes at approximately eighty percent; only the remainder of twenty percent is processed by the jewelry industry. This is because, to date, there is no commodity besides diamonds that has a higher value in a given space. – See diamonds, precious metals, colored stones, jewels, carat, button cutter, polygon, magic, value relativity.
