Angelite, otherwise known as Anhydrite in a mineralogical context, is an evaporite mineral often found in association with gypsum, sulphur, halite, calcite, and dolomite. It is a member of the Anhydrous Sulfate Group, with chemical formula CaSO4 (Calcium Sulfate). Anhydrite and gypsum are the only rock forming sulfate minerals. Anhydrite has a hardness of 3-2.5 on the Mohs scale (so fairly soft) , and a pearly or vitreous luster. In pure form, this mineral is colorless, with color coming (as usual) from minute quantities of other elements within the crystal lattice. [Mineralogy, Perkins]

Spinel (MgAl2O4) is a magnesium aluminum oxide mineral, with a hardness of 8 on the Mohs scale. It occurs in a range of colors, from colorless to black, with red, lavender, blue, white and others possible. It has a long history of use as a gemstone. In nature, it is formed by high-temperature metamorphism of carbonates or schists, and is often associated with calcite, dolomite, garnet, corundum, diopside, olivine, and other dense minerals.
