Green amethyst (green quartz or prasiolite) occurs naturally under certain geologic conditions. On the California-Nevada border, just north of Reno, amethyst, citrine, and green quartz occur together in clusters of crystals. Heating via high-temperature, volcanic activity may be responsible for the subsequent color changes to citrine or green quartz. Green quartz gemstones are found in varying shades of green, greenish yellow and yellowish green. Although it can occur naturally, the spring-like green color of this oval faceted quartz is often achieved by irradiating and heating pale Brazilian amethyst.
