A sheet of clear selenite is held by a sleek and contemporary, nickel-plated stand. Disclaimer: Selenite is a natural crystalline material. By its sheer nature, imperfections such as other mineral deposits, which may appear as colored sections or varying crystalline structures, are not only expected but indeed add to the beauty of the piece. The softness of selenite may result in the separation of sections of crystal, which can be reattached with the use of a clear adhesive.
