Grossular is a calcitic garnet (neosillicate) with the chemical formula Ca3Al2Si3O12. The given mystery mineral was originally thought to be a spessartine, another member of the garnet group, but turned out to be a grossular solid-solution. Physical test was initially conducted and the data was inputted into the Dyar and Gunter Mineral Database resulting in the mineral most likely being spessartine. In order to confirm the validity of the physical test, RAMAN spectroscopy and X-ray powder diffraction were conducted on the mystery mineral and the data was than compared to a mineral database. From these tests, it was confirmed that the mystery mineral was a grossular solid-solution and that the physical test is not most accurate method of identifying a mineral. An analysis of the industrial uses of garnet and an economic analysis of the garnet production industry was conducted. It is predicted that the garnet industry will grow 3%-5% because of garnet's minimal health risks and many industrial uses, especially as a blast cleaning agent and filtration medium.
