Greetings, We are a Gemological Laboratory. Under your Section V. under "Varietals" you (2) the use of the term ''green amethyst'' to describe prasiolite." Please note that this is incorrect. Prasiolite is a very rare stone and these green quartzes are actually amethysts that have been irradiated to the green color. To be accurate your section should read: "(2) the use of the term ''green amethyst'' to describe irradiated green quartz."
