The most expensive metals in the world


The jew­el­ry world has many dif­fer­ent met­als, the most famous of which are gold, sil­ver and plat­inum. But the fact that every­one in the world knows them does not mean that they are the most expen­sive. There are met­als whose price seems unre­al­is­tic.

Types of expensive metals

Among expen­sive met­als, nat­ur­al and arti­fi­cial­ly derived are dis­tin­guished. The first type includes osmi­um, rhodi­um, ruthe­ni­um, plat­inum, gold, etc., and the sec­ond type has only two — Osmi­um 187, Cal­i­for­nia.

artificial metals

- 252 Cal­i­for­nia. Hold on tight — the met­al is worth approx­i­mate­ly $6.5 mil­lion per gram. It began to be pro­duced in the mid­dle of the last cen­tu­ry at the Uni­ver­si­ty of Cal­i­for­nia, hence the name. Only 6 grams have been pro­duced through­out his­to­ry. Since the met­al has radioac­tive prop­er­ties (and what else: the pow­er of one nuclear reac­tor is equal to one gram of met­al ener­gy), it is used to scan parts of reac­tors and parts of air­craft, heli­copters in order to find faults.

- Osmii 187. It has a deep dark gray col­or. In gen­er­al, at its core, osmi­um is the small­est sand, which slight­ly gives off pur­ple. The met­al has an incred­i­bly high den­si­ty. Used to cre­ate pre­ci­sion instru­ments. Osmi­um is mined for almost a whole year.

natural metals

- Ruthen­ian. The mate­r­i­al was dis­cov­ered in a near­by XIX cen­tu­ry. It is very brit­tle despite the fact that it is hard and infusible. Pro­duced only in South Africa. The price varies from 8 to 10 dol­lars per gram. Has a sil­ver gray col­or.

- Osmi­um. Its cost also depends on the qual­i­ty; they ask for 12 to 15 dol­lars per gram. Col­or — del­i­cate sil­ver-white, gives blue. Despite the beau­ty, Jew­el­ers do not use it for their own pur­pos­es, all osmi­um is extreme­ly tox­ic and can cause great harm to the body.

- Pal­la­di­um. The cost is from 30 to 33 dol­lars. Col­or is a beau­ti­ful light sil­ver. It is char­ac­ter­ized by plas­tic­i­ty and fusibil­i­ty. A very impor­tant advan­tage is that the mate­r­i­al is resis­tant to cor­ro­sion and does not fade over time. It is almost impos­si­ble to find acces­sories made of pal­la­di­um alone; more often it is com­ple­ment­ed with white gold jew­el­ry.

- Plat­inum. The met­al is val­ued at about $30 per gram. Typ­i­cal light sil­ver col­or. It was con­sid­ered less valu­able than even sil­ver due to its refrac­tori­ness, even the name trans­lates as “tiny sil­ver”. It is quite dif­fi­cult to get plat­inum because it does not exist in the nat­ur­al envi­ron­ment in its pure form, only in com­bi­na­tion with oth­er met­als. To iso­late 1 gram from alloys, it is nec­es­sary to process approx­i­mate­ly 3 tons of ore. Plat­inum acces­sories are very pop­u­lar among Asian nations.

- Gold. The cost is approx­i­mate­ly 40 dol­lars. The col­or depends on the type of gold, most often you can find gold­en yel­low. This is prob­a­bly the very first met­al dis­cov­ered by mankind. With­out the addi­tion of oth­er met­als, gold has an incred­i­ble plas­tic­i­ty, so that it can be smoothed into a very thin film. For a very thin 28 km string, only 10 grams of gold is used.

- Irid­i­um. The cost per gram is approx­i­mate­ly $44. Dif­fers in hard­ness, but at the same time fragili­ty. Used in alloys with plat­inum. Resis­tant to cor­ro­sion. Met­al is very dif­fi­cult to process. One of the met­als found on mete­orites.

- Rhodi­um. One gram costs about $70. To get the met­al, you need to smelt plat­inum. It was first opened in XIX cen­tu­ry. Rhodi­um acces­sories do not exist as such — it is only used to cov­er sil­ver or gold jew­el­ry to give a daz­zling shine. The advan­tage of rhodi­um is that it is absolute­ly resis­tant to cor­ro­sion and mois­ture.
