In 1951, the journal Rocks and Minerals revised its column The Amateur Lapidary and asked Sinkankas to be the author. It was this assignment that launched his career in writing about gems and minerals. He became a frequent contributor to the column and also wrote other articles for the magazine - nearly 35 articles appear under his name.
The Mineralogical Record was first published in 1970, on the initiative of John S. White, a curator in the Smithsonian Institution's Department of Mineralogy, with the aim of filling the gap between scientific mineralogy journals (which began at that time to look more like solid state physics and chemistry than conventional descriptive mineralogy) and purely amateur magazines.

Mandarino's interest in minerals began when he was a child, collecting rocks around the Chicago area. Encouraged by one of his schoolteachers, he would make trips to see the mineral collection at the Field Museum of Natural History. By the age of 18, he had already published articles on minerals in Rocks and Minerals magazine.
The Folch Collection was known during the period 1960-1980 as one of the best private mineral collections in the world. It was famous for its size (over 15,000 specimens), the quality of the pieces, the large number of classic specimens, which are now almost impossible to obtain, and the style of the collection, which is surprisingly 'modern'.
Normative mineralogy is an estimate of the mineralogy of the rock. It usually differs from the visually observable mineralogy, at least as much as the types of mineral species, especially amongst the ferromagnesian minerals and feldspars, where it is possible to have many solid solution series of minerals, or minerals with similar Fe and Mg ratios substituting, especially with water (e.g ...
Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish the various species. Within a mineral species there may be variation in physical properties or minor amounts of impurities that are recognized by mineralogists or wider society as a mineral variety.
