Prasiolite is a green variety of quartz. The two components of its name are derived from Greek roots meaning leek-green stone. The color is produced by irradiating or heat-treating amethyst containing ferrous iron (Fe2+) to approximately 500oC, although some natural prasiolite has been found.

Prasiolite is an easy-going, gentle, pastel-green stone. Although it's found naturally, it's extremely rare. So... we nudge Mother Nature! As with many stones, heat treatments are transforming. Amethyst from Montezuma, Minas Gerais, Brazil was first found to turn green when it was heated. Since then material from Four Peaks, Arizona; Zimbabwe; Ceará, Brazil; and a location in California have also been found to turn green upon treatment. Because prasiolite is a variety of quartz, it's a seven on the scale of hardness and therefore extremely wearable.
