THE WORLD'S RAREST MINERALS
Thanks to research, all species of rare minerals existing to date have been categorized.
These 2550 minerals have a higher rarity than expensive diamonds or gems
Many of these foreign minerals are very difficult to expose, because some are prone to melt, evaporate or dehydrate. And some, like vampires, gradually decompose when exposed to sunlight.

What is most surprising about these minerals are the revelations of the subway conditions in which they were formed.
Scientists Robert Hazen of the Carnegie Institution and Jesse Ausubel of Rockefeller University "On the Nature and Significance of Rarity in Mineralogy"
Significance of Rarity in Mineralogy"
Establishes the first system for categorizing rarities in the mineral kingdom
provides mineralogists with a framework that parallels that used to understand rare plant and animal species.
There are minerals that are considered "rare" but do not meet all the conditions according to the planet earth to be rare minerals.
"Diamond, ruby, emerald and other precious gems are found in numerous localities and are sold in commercial quantities, so they are not rare in the sense used in this contribution.
Example of a really rare mineral
Each rare mineral fits into one or more of four categories:
1) Unique conditions that created the mineral
Some minerals are rare because, although they are formed from the most common ingredients, they must be cooked under exquisitely controlled conditions.
Example
the mineral hatrurite
is formed from three of the most abundant elements on Earth: calcium, silicon and oxygen. But hatrurite forms only in a very restricted environment with temperatures above 1250 ° C.
2) Planetary constraints:
Minerals composed of very rare elements under pressure-temperature conditions that are rarely found in near-surface environments.
3) Ephemel minerals:
Certain minerals are compounded under unusual conditions, for example radically cold or dry environments, however they then simply melt, evaporate, or dehydrate once exposed to different conditions in the area..
4) Places geologists rarely sample
In the fourth category remain rare minerals that simply come from undersampled areas, from extreme environments such as the flanks of erupting volcanoes, frigid and remote areas of Antarctica or the deepest reaches of the seas.
Biological vs. mineralogical rarity
Minerals do not evolve in this way although an intriguing and still little explored aspect of mineralogy is how trace elements and minor elements and isotopes in common mineral species have varied throughout earth's history in response to conditions. changing near the surface, unlike mineral species biological species that do not become extinct however are constantly evolving in some cases not so gradually in new forms, rare minerals on the other hand may disappear from the earth for a time just to reappear when the necessary physical and chemical conditions reappear
Often point to extreme compositional regimes that can arise in Earth's shallow crust;
Are valuable in understanding Earth as a complex evolving system in which pervasive fluidrock interactions and biological processes lead to new mineral-forming niches
Are key to understanding the diversity and disparity of Earth's mineralogical
environments;
Increase the likelihood of finding novel crystal structures and advancing crystal chemistry
