Amazonite is a gem found most commonly in Brazil, but also in Colorado, Eastern Canada, Italy, and Russia. It is named after the Amazon Basin because of its prominence in Brazil, though it is actually not found in that particular part of Brazil.
Amazonite is primarily known for having a soothing effect on the brain and nervous system. The result is relief of fear and anxiety, and an increase in courage. It is also believed to bring happiness to married life, presumably because your personal anxiety harms your relationships with others.
Amzonite is also believed to be good for your skin. We all know from experience that anxiety can cause outbreaks and accelerate the ageing process, but Amazonite relieves that anxiety.
If you are a person who's too high-strung, overly nervous, and prone to stress, Amazonite may be an important gem for you.
