Green amethyst is a rare precious stone that is used to make various types of engagement rings. Green amethyst engagement rings are said to open the crown chakra and third eye chakra, meaning that they are mostly used to increase one's sense of empathy.
Green amethyst is a misnomer. The proper name is Prasiolite. It is formed when amethyst is heated under extreme conditions, causing the color change. Prasiolite is said to prevent drunkenness and help a wearer overcome an addiction.
People looking for unique and unconventional engagement rings can opt for green amethyst. Being less expensive than colored diamonds, the engagement rings are preferred by those looking for a colored stone at significantly less than the price of a colored diamond.
