Prasiolite beads: where do they come from?
This gemstone is partly processed by nature and partly by humans. Prasiolite beads have a pre-green color and the name literally means 'leek stone'. Since the 1950s, prasiolite has been made in Brazil. In the mine Montezuma in the Brazilian state of Minas Gerais, amethyst and yellowish quartz are found. By burning at 500 degrees Celsius of this amethyst and yellowish quartz, the pre-green color is created. Prasiolite is therefore also called 'green amethyst'.
A similar process takes place in nature. Where geodes with amethyst have been formed in (old) volcanoes, there is also the chance that you will encounter prasiolite. Usually in geodes that are strongly heated and in which the amethyst is transformed into prasiolite. In the meantime, rock crystal can also be given the pre-green color. This is done by means of radiation.
The gem is not only found in Brazil but also in the United States, Madagascar, Namibia, Sri Lanka, Russia and Finland. So on the eye the gem is confused with beryl, peridot and tourmaline.
