Villiaumite Specimen #6 Type_Accessory outdated ideas and constraintsThis very rare Villiaumite specimen is from the Kola Peninsula, Russia. You will receive the exact Villiaumite crystal pictured. Villliaumite was first found in 1908 in Guinea, and is named after French explorer Charles Maxime Villiaume. It is a member of the Halite group, is soluble in water and is toxic in this form as sodium fluoride in liquid form is easily absorbed by the body, so these specimens should be handled with care and kept dry.
