Green amethyst, also known as prasiolite, is a unique and captivating gemstone that exhibits a stunning green colour. It is a variety of quartz and derives its green hue from the presence of iron in its crystal structure. Green amethyst is relatively rare compared to its purple counterpart.
The name “prasiolite” originates from the Greek words “prason” meaning “leek” and “lithos” meaning “stone,” reflecting the gemstone’s resemblance to the vibrant green shade of a leek. Initially, the green colour of amethyst was achieved by heat treating natural purple amethyst, but recently, deposits of naturally occurring green amethyst have been discovered.
