Amazonite is a green variety of microline (sometimes applied to Orthoclase) feldspar and recent studies suggest that the blue-green colour comes from small quantities of lead and water in the feldspar.

Possible locations for Amazonite in Australia could include Broken Hill, Yancowinna Co., New South Wales or Central Desert Region, Harts Range in the Northern Territory. Other notable locations where Amazonite is found around the world include Pikes Peak, El Paso Co. – Colorado USA and Russia.

This specimen was purchased from Crystal Castle located in northern NSW near Byron Bay.
