Mineralogist
A mineralogist was a scientist who studied in the field of mineralogy.

In 2267, while fighting a Gorn captain on the planet Cestus III, Captain James T. Kirk noted that the planet had large quantities of sulfur and diamond. Their abundance lead him to comment that it was a "mineralogist's dream." ()
