Germanium Phone Cases - iPhone and Android
Description: A prime Germanium design. Germanium is a chemical element with symbol Ge and atomic number 32. It is a lustrous, hard, grayish-white metalloid in the carbon group, chemically similar to its group neighbors tin and silicon. Pure germanium is a semiconductor with an appearance similar to elemental silicon. Brought to you by Periodic-Tees.com
