Amethyst is a beautiful violet color and is the most valuable type of quartz. It is a good substitute for blue sapphire. The darker the color, the more effective it is.

Amethysts are mined in Brazil and Uruguay, but are also found in the USA, Sri Lanka, Myanmar (Burma), India, and Mexico. The Brazilian amethysts are considered the best, but the ones from Sri Lanka and India are also good quality. Imitation amethysts are often made from glass or synthetic sapphires. Synthetic amethyst is usually made in Russia.

Amethyst can be used to increase financial gain, for general physical well-being, position, and social status. It is said that amethyst will become brighter if it is placed next to a poisonous substance. It is also believed that the stone will change color if the wearer becomes ill.
It can be used with good benefit by social workers, scientists, mathematicians, scholars, and by those engaged in travel, public relations, entertainment, and fashion.

Amethyst is said to be good for those under Pisces or Aquarius, but can also be worn by those under Capricorn.
