Amazonite is a gemstone variety of green microcline, a feldspar mineral. It is named after the Amazon River in Brazil, though surprisingly no deposits have been found in that location. The lively green or blue-green color is extremely attractive. Amazonite is said to calm one's emotions and soothe nerves, and to enhance creativity and the ability to express oneself. Perhaps the strongest recommendation for its metaphysical power is that amazonite is said to make your married life happier.
