Searlesite is a sodium borosilicate named after John W. Searles (1828-1897), who realized the valuable borax content of a dry lake in the Mojave Desert which now bears his name: Searles Lake. Foshag (1934) studied the chemistry and morphology of searlesite from this occurrence in Nevada, which is now part of The Rhyolite Ridge Lithium-Boron Project under development by ioneer™. Further specimen production is not likely.
Searlesite forms colorless prismatic crystals to 2 mm with equally sized brown baryte crystals. The matrix is a clay-bearing marl. From the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona. Laskowski self-collected this specimen June 18, 2001.
