Amazonite stone is also referred to as “Colorado jade” or “Pikes Peak jade” because of its resemblance to jade. Amazonite can be pale green, but also blue-green, turquoise or yellow-green and can also have white streaks. The colour of Amazonite is due to the presence of lead within the stone and colour variation may exist within a single stone. Amazonite is a mineral of limited occurrence and is present in parts of Brazil, Colorado and Virginia in the United States, Australia and Madagascar.
