Amazonite is a stunning-coloured crystal found in shades of turquoise, blue-green, or deep blue. It is from the family Microcline, also referred to as an alkali feldspar mineral. Amazonite was first recorded in 1847 by A. Breithaupt, but history shows many cultures have used it for at least 4,000 years. Ancient Egyptians considered it sacred and used this stone for a unique scarab ring placed in the tomb of King Tutankhamen. Amazonite has been discovered in the forms of armour, protective amulets, and writing slabs.
