Uses: Reflectivity, including jewelry, mirrors, and other reflectors, and automotive uses. Iridium is one of the densest metals. It also has one of the highest melting points and is the most corrosion-resistant element. Uses: Pen nibs, watches, jewelry, compasses, electronics, medicine, automotive industry. Major Source: South Africa.
Osmium basically is tied with iridium as the element with the highest density. This bluish metal is extremely hard and brittle, with a high melting point. While it's too heavy and brittle to use in jewelry and gives off an unpleasant odor, the metal is a desirable addition when making alloys.
Uses: Pen nibs, electrical contacts, hardening platinum alloys. Other elements are sometimes considered to be precious metals. Rhenium is commonly included on the list.
Some sources consider indium to be a precious metal. Alloys made using precious metals are themselves precious. Copper sometimes is listed as a precious metal because it is used in currency and jewelry, but copper is plentiful and readily oxidizes in moist air, so it is not particularly common to see it considered "precious.

Because it was first chanced upon in silver mine in South America, platinum was named as such, after the Spanish word "platina", which translates to "little silver". Palladium - William Hyde Wollaston, an English chemist and physicist, discovered palladium in in samples of platinum ore obtained from South America. In , the 1 oz. All coins, which have legal tender status in Canada, consist of 0. The same can be said of bismuth, which has a mass abundance half less than that of palladium, but with a price of only a little more than a tenth of tellurium's price.
In terms of mass abundance, expressed in parts per billion ppb , here's how the nine precious metals are ranked rare to rarest : 9th: silver 75 ppb ; 8th: palladium 15 ppb ; 7th: gold 4 ppb ; 6th: osmium 1.
