Mineralienatlas (name for mineral atlas) is the platform for people interested in mineralogy, geology, palaeontology and mining since 2001. We operate a significant database for minerals, fossils, rocks and their localities. Mineralienatlas is not limited to a section. We bring together information and inform comprehensive.

To complete our information constantly, we need your support. With us, everyone can and should participate. Currently Mineralienatlas is used and expanded by 10530 members. Every month hundreds of thousands of visitors use our website as an information source.

... Von den weltweit weni­gen Fun­dorten (darun­ter Brasilien, Sri Lan­ka und Zim­bab­we) sind die rus­sischen Alexan­drite die hoch­w­ertig­sten, da sie im Ge­gen­satz zu den meist weniger kräftig ge­färbten Stei­nen aus den an­deren Län­dern ihre Farbe von einem in­ten­siv­en smaragd­grün zu einem tie­fen pur­pur­rot wec ... more... Von den weltweit wenigen Fundorten (darunter Brasilien, Sri Lanka und Zimbabwe) sind die russischen Alexandrite die hochwertigsten, da sie im Gegensatz zu den meist weniger kräftig gefärbten Steinen aus den anderen Ländern ihre Farbe von einem intensiven smaragdgrün zu einem tiefen purpurrot wechseln. Die Originalfundstelle im Ural war nach mehreren Jahrzehnten Abbau erschöpft und nur wenige dieser berühmten Alexandrite tauchen ab und zu auf dem Markt auf. Neuere Funde stammen aus Zimbabwe, Sri Lanka, Tansania, Tasmanien, Indien und Myanmar (Burma), besitzen jedoch nicht den starken Farbwechsel der russischen Alexandrite. Im Jahr 1987 entdeckte man in Hematita (Minas Gerais) in Brasilien Alexandrite, welche nahe an die Qualität der historischen russischen Steine herankommen und einen attraktiven ...

This year not only the name seems to change away from the "Munich Mineral Show" changing to "The Munich Show". The new exhibition management, led by the young Mr. Keilmann seems not quite knowing where to go or has something bigger in mind. One can imagine something in "Munich Mineral Days", it is difficult in the name "The Munich Show". The new show management seems to leave the common way, to keep all options open with a new name. - A comment and fair report written in german language by Stefan Schorn

Min­er­al por­trait gar­netThis portrait mainly deals with the 6 classic garnets, their amazing history, the world’s best known classic and modern localities and deposits and their use as a gems or abrasives. It also deals with the common belief related to the non-existence of blue garnets and its refutation proven by new finds. A separate chapter deals with synthetic garnets. But it also deals with the mix up of definitions, groupings and old and unnecessary terms, which have finally been terminated or brought to a common denominator.

In 2012 the IMA (CNMNC) has defined garnets as members of the Garnet Supergroup, which include all minerals isostructural with garnet regardless of what elements occupy the four atomic sites; i.e. the supergroup includes several chemical classes . Those minerals are closely related to each other and may form a series with each other. Some garnets form intermediary minerals between each member, and may even be intergrown within a single crystal.

With the publication of the new nomenclature of the garnet supergroup, the term “garnet group” does not have its meaning anymore and the intermediate working term “Garnet superstructural group” has been replaced by “Garnet Supergroup”.
There are 32 approved species and 5 “candidate” species waiting on approval. The 32 species are subdivided by their Z-charge into 29 species, which belong to 5 groups and to 3 single representative species.
One of those 5 groups is the “Garnet group”, consisting of the 6 former (classic) garnets Pyrope, Grossular, Spessartine, Almandine, Uvarovite and Andradite plus 8 rarer garnets , as Menzerite-(Y), Eringaite, Goldmanite, Momoiite, Knorringite, Calderite, Majorite and Morimotoite.
