Brazil amethyst production quantity is much more than other amethyst areas. The amethyst has its hardness (7), its moderate refraction and its weight in common with the other quartzes, but the crystal structure is different, and it is most unconventional. The construction is stratified, as a result of which areas and lamellae of varying colour intensity often come about. This explains why there are relatively few large cut amethysts of an evenly distributed dark colour, in spite of its having been found so abundantly in all parts of the world. Some amethysts pale almost to colourlessness in daylight. The reason for this has not yet been discovered, but it is possible to re-colour them by means of radium radiation. The fact that these stones can lose their colour makes it obvious that amethyst jewellery should not be worn while sunbathing, in a solarium or in a discotheque with black light. Sudden changes of temperature can also be harmful to the stone.
