Amazonite, sometimes called “Amazon stone”, this mineral is limited in its existence. Amazonite is blue-green to pale green stone in the feldspar group. It is found in the United States, Australia, Brazil, Madagascar and Russia's Ilmen Mountains. The first Amazon stones discovered had been obtained along the shores of the Amazon River, giving these multicolored greenish stones their names. This stone is also believed to be a potent talisman of healing and prosperity. In the early Mesopotamian, Indian, Egyptian, and Sudanese cultures, evidence suggests Amazonite had been cut into beads and used in jewelry. It had been used as a decorative material and in some important death rituals. It was carved and cut into tablets for the Egyptian funerary text, Book of the Dead. There was also an Amazonite ring found in Tutankhamen’s treasures. It was believed to be the third stone in the breastplate of the Jewish High Priest. In today’s culture, pale azure blue Amazonite is known as the lucky "Hope Stone".
