About the stone

Prasiolite is a transparent, pale leek-green variety of quartz whose name comes from the Greek words for “leek” and “stone”; naturally green material is rare, and nearly all commercial stones obtain their color through heat treatment or irradiation. No single discoverer is universally credited, but its modern gemstone history began in the 1950s when amethyst from Montezuma, Minas Gerais, Brazil, was found to turn green when heated. Brazil remains the principal commercial source, while naturally occurring material has been reported in Poland, Canada’s Thunder Bay region, and Namibia. Other names include “green quartz,” “vermarine,” and the alternative spellings “praseolite” and “praziolite”; the popular trade name “green amethyst” is misleading because amethyst is, by definition, purple. Modern crystal lore associates prasiolite with compassion, self-acceptance, renewal, and the heart chakra.

It is thought to bring a calm, steady presence that allows divine love and a sense of unity to be felt without leaving one feeling scattered or ungrounded.

Many people simply find that wearing or holding it brings a soothing, restful feeling that supports their overall sense of well-being.

Care and handling

Prasiolite is a quartz and quite durable, with a hardness of 7. Clean it with lukewarm water, mild soap, and a soft cloth. Because most prasiolite is heat-treated amethyst, keep it out of prolonged strong sunlight and away from high heat, which can fade its color. Avoid harsh chemicals and sudden temperature changes. Store it apart from harder gemstones to prevent scratches.

Individual experiences with Prasiolite vary, and its effects are deeply personal. Approach it mindfully and with an open heart, letting it be a gentle companion on your path toward self-love and compassion.
