Green Chevron Amethyst Tumbled Stones
Although this material is often sold as prasiolite or green amethyst, both names are inaccurate. Green amethyst is actually a misnomer because the word 'amethyst' which comes from Ancient Greek amethustos meaning not drunken, is in itself a definition of the purple variety of the mineral quartz. Although amethyst is mostly widely recognised as a distinctively purple coloured stone, crystals can be pale pinkish violet to dark blue-violet, they can exhibit shades of red and sometimes even grey. Amethyst does not however occur in green or any other colour.
Although natural prasiolite does exist it's extremely rare hence is not used for gemstones or other lapidary purposes. When amethyst is heated it turns yellow but material from a small number of locations worldwide turns into more of a green colour and it's this which is used to produce this type of prasiolite. Very rarely the colour is produced naturally through radiation and this material which often has a very subtle green colour is correctly known as prasiolite.
Almost all of the prasiolite that's available for sale is produced in Brazil. In recent years chevron amethyst (also known as banded amethyst) has been used most likely because the distinctive white markings make the stone more interesting. Chevron amethyst which is named because of its distinctive chevron-like markings is a combination of amethyst and milky quartz. As far as we are aware the unique colour of this stone is produced solely by exposure to heat.
Our prasiolite tumbled stones are a medium sized stone but weights and sizes do vary from piece to piece. For this reason we have split them into small and medium.
