Manganese – Wikipedia
Manganese is a chemical element with the symbol Mn and atomic number 25. It is not found as a free element in nature; [not verified in body] it is often found in minerals in combination with iron.Manganese is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels.
Opal – Wikipedia
Opal is a hydrated amorphous form of silica (SiO 2 ·nH 2 O); its water content may range from 3 to 21% by weight, but is usually between 6 and 10%. Because of its amorphous character, it is classed as a mineraloid, unlike crystalline forms of silica, which are classed as minerals.It is deposited at a relatively low temperature and may occur in the fissures of almost any kind of rock, being

Mineralogy – Wikipedia
Mineralogy is a subject of geology specializing in the scientific study of the chemistry, crystal structure, and physical (including optical) properties of minerals and mineralized artifacts.Specific studies within mineralogy include the processes of mineral origin and formation, classification of minerals, their geographical distribution, as well as their utilization.
Mineral Properties, Photos, Uses and Descriptions
Minerals are materials that meet five requirements. They are: 1) naturally occurring, 2) inorganic, 3) solids, 4) with a definite chemical composition, and, 5) an ordered internal structure. Mineral Menu Andalusite Anhydrite Apatite Arsenopyrite Augite Azurite Barite Bauxite Benitoite Beryl Biotite

Variscite – Wikipedia
Geology. Variscite is a secondary mineral formed by direct deposition from phosphate-bearing water that has reacted with aluminium-rich rocks in a near-surface environment. It occurs as fine-grained masses in nodules, cavity fillings, and crusts.Variscite often contains white veins of the calcium aluminium phosphate mineral crandallite.. It was first described in 1837 and named for the

What is the difference between a rock and a mineral?
A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite.A rock is an aggregate of one or more minerals, or a body of undifferentiated mineral matter.

Nonetheless, emerald continued to be listed as the preferred species name for many
