Iridium prices have fluctuated between US$ 300 and US$ 1100 per troy ounce over the past decade. Prior to 2010, the price for iridium was fairly stable at around US$ 450 per ounce, however, this changed in the first half of 2010 as a shortage of the metal led prices to over 60 percent. By the end of the year, iridium was selling for over US$ 1000 per troy ounce.
This sharp increase in iridium prices was driven by new demand from the light emitting diode (LED) industry. Growth in the LED market led to greater demand for iridium alloy crucibles, which are used to grow substrate materials for LED production. The results was a four-fold increase in iridium consumption between 2009 and 2010.
Like most other metals, though, slowing demand and over-supply brought prices for iridium sponge and iridium powder downward in 2013. By December the market price for commercial 99.9% min. iridium was again under US$ 500/kg.
