Beautiful soft pink natural Tourmaline(1ctw, Type 2, SI, USA) hand set in sterling silver studs. The national gemstone of the United States, tourmaline is found all over the world and in various colors. Tourmaline is the most colorful of all gemstones because, according to an ancient Egyptian legend, it passed through a rainbow on its journey to Earth and brought all of the colors of the rainbow with it. Tourmaline is actually a group of gem species with the same crystal structure and slightly different chemical properties, which account for all of its different colors. All tourmalines are silicates that contain aluminum, boron, and fluorine, in addition to a variety of other elements that give the different species their different appearances. Major tourmaline species include liddicoatite, dravite, uvite, schorl, and the most important one--elbaite--which encompasses most gem tourmalines and the widest range of gem-quality colors.Please ask questions
