We are pleased to announce the imminent release of our one troy ounce ingots of thulium. Thulium is the second most rare of the rare earth elements behind promethium. As promethium is radioactive and will not be one of our products, thulium is the rarest of our rare earth series. Despite it's rarity and cost, there are important industrial uses of thulium in solid state lasers and x-ray machines. Own what's rare.
