There are millions of minerals in the world and even I don't know them all. Thank goodness for Wikipedia, Google, and the many gem and mineral books out there to help us learn.
Speaking of learning, I am going to share three minerals in my collection that you may have never heard of--unless you follow me closely and have seen me talking about these awesome minerals.
Trolleite is a pretty rare mineral that is a light green colorless or bluish-green mineral. However, when it's included in another mineral--such as my pieces, it's a darker blue.
It gets its color from scorzalite, according to Hans Gabriel Trolle-Wachtmeister, a Swedish attorney general and chemist from who the stone gets its name.
Vanadinite may look delicious, but it's the result of a chemical alteration to a pre-existing material and is considered a secondary mineral. A Spanish mineralogist made the initial discovery in Mexico in 2018.
At first, he thought it was a brown lead that had a new element in it. After some more discoveries over time, it was discovered that Vanadinite is in the Apatite mineral family and is often found in the oxidation area of lead deposits in dry climates.
Jeremejevite is a mineral that I came across back in 2012 and learned that back then it was the 2nd rarest mineral on the planet.
Since then, more deposits have been discovered and it's no longer the 2nd rarest but still pretty rare. The ones you see image above came to me in the form of a gift. Jeremejevite is either colorless, sky blue, or pale yellow. It's often mistaken for aquamarine.
