But, the science of mineralogy is important in other ways. Three varieties of beryl are shown below in Figures 1.12, 1.13, and 1.14. After all, most of the crystalline materials used in modern electronic applications today are synthetic. They are commonly called simulants and include, among others, forms of cubic zirconia, titanium oxide and strontium titanate that look something like diamonds. The word mineral means different things to different people. All minerals, like all materials, consist of one or more elements, the building blocks of all matter.
