Agpaitic minerals are those found in unusual igneous intrusive rocks that contain alkali metals and high concentrations of unusual metals such as titanium and zirconium. These rocks are called agpaites and there are only a few localities around the world that are identified as agpaites. At both sites, raite forms beautiful acicular crystals arranged in sprays, fans, spherulites, rosettes and as crusts. The color is golden-brown to red or even violet with a silky luster. It is associated with other rare minerals and although hard to find, it is certainly a cool mineral to have in a collection.
