Alexandrite
Amazonite[edit | edit source]
The name of this mineral derives from Amazonia, where native peoples used green stones as amulets. It turned out that those stones were, in fact, green jadeites, but the name stuck to the green to bluish green opaque gemstone variety of microcline.[1]
Amazonite is commonly mistaken with chrysoprase, serpentine or green jadeite.
