Prasiolite (Greek - leek-green stone) is a rare stone in nature.
Prasiolite is the gorgeous, green variety of quartz, also called “vermarine,” “amagreen,” “lime citrine,” “green quartz,” or “green amethyst” (erroneously). Nearly all natural specimens have come from a little Brazilian mine ever since 1950, but this crystal has also been found in Poland, Canada, Tanzania, Namibia, Zambia, Zimbabwe and the United States (Nevada, Arizona and New Hampshire).
It rarely occurs in nature, but when it does, it is typically found in volcanic and igneous rocks, accompanied by amethyst. It is an oxide mineral that exhibits a variety of shades of green, a trigonal crystal system, no cleavage, a brittle tenacity, a Mohs scale hardness of 7, and a specific gravity of 2.65. It ranges from transparent to almost opaque.
Prasiolite is scratch resistant and durable, and is usually sold to be used in daily-wear jewelry settings. People often create it synthetically by heat treating amethyst, and nearly all prasiolite currently available on the market results from ionizing radiation and heat treatment. Most amethyst turns brown, yellow or orange when heat treated, but specimens containing special iron compounds turn green, instead.
In the metaphysical world, prasiolite is associated with the element of earth, the astrological signs of capricorn and scorpio, and the energies of love, power and inner vision
