Amazonite is mainly recognized as a semi opaque blue-green mineral. They can form the largest known crystals of any mineral. It is formed in deep-sea igneous rocks that once cooled very slowly.
Within many of the stones there are also white streaks of color which is caused by Albite, something that has grown along with this Amazonite into a crystal variety. The highest quality of this gemstone is determined by how much of this Albite is in the gemstone. The more solid in the green or blue color the specific gemstone has, the higher the quality.
Ancient Egyptians made this stone famous by using it for their jewelry and ornamental pieces. It is named the Amazon Stone, after the Amazon River, but it was not found near the river. It is mined throughout other places in Brazil, though.
Fun fact: Amazonite was discovered as beads and was also found in jewelry that was in King Tut’s tomb.
The most important source of Amazonite is India. Especially fine specimens are also found in Colorado. Other sources for Amazonite include various areas around Madagascar, Namibia, Brazil, Zimbabwe, Canada, India, Tanzania, Australia and the Russia. Amazonite can also be found in the United States, mostly near Pike’s Peak, Colorado, and also in Maine.
