Amazonite is a type of feldspar mineral - like moonstone, sunstone, and labradorite - which is known for it's bright blue-green colour. The really odd thing about amazonite is that we still don't know fore sure exactly what causes that colour. Originally, it was thought to be copper, but these days it is thought to be either lead or iron. For obvious reasons, this means amazonite should not be infused into anything intended to be ingested. (ie. "Don't put it in water you plan to drink.")
Though it is not a very common stone, Amazonite is a very widely-spread occurrence. Some of these mines can be found in Afghanistan, Australia, Brazil, Canada, China, Ethiopia, India, Libya, Madagascar, Mongolia, Namibia, Norway, Poland, Russia, South Africa, Sweden, and USA. Ours happens to originate from India.
Amazonite was named for it's "discovery" in the region of the Amazon river. However, it's now thought that those stones may have not actually been what we now classify as Amazonite, and no one knows what became of those particular stones, so we'll never really be sure. Though its use might reach back as far as ancient Egypt, it was first classified as its own mineral in the 1700s.
Amazonite is believed to be able to create a powerful shield between you and negative or damaging forces. It is thought to help with empathy, emotional processing/awareness, and processing grief. As well, it has helped writers and artists access their creative sides or their muses. It is thought to open the mind and help facilitate healthy choices.
