Amazonite is a green or blue-green gem variety of Microcline which is Feldspar. Lead and water deposits are thought to account for the luscious green colour. The stone has creamy white striae through it which give a mottled or stripy character to the surface once polished. |
It was named after the Amazon River from which certain green stones were formerly obtained. However, it is doubtful whether Amazonite occurs in the Amazon area although it is found in other areas of America and Russia.
