Also known as Mount St. Helens stone, helenite is a man-made stone that originates from the ashes of the Washington State Mount St. Helens eruption in 1980. While the volcanic ash was being removed, it was discovered that it contained glass particles that turned a beautiful green color when heated. This glass is commonly made and fashioned into jewels that may be green, red or blue.
