The transparent, dark purple balls of Maraba amethyst have a diameter of 6mm, the entire amethyst strand has a length of about 40cm.
In analytical stone healing according to Michael Gienger, the dark amethyst is used to strengthen alertness, inner peace and sense of justice.
The name amethyst is derived from the Greek word amethystos (counteracting intoxication) and refers to the traditional belief that with an amethyst one is protected against the intoxicating effects of wine and other alcohol. Spellings such as Amathyst, Amethist, Ametist, Ametyhst, Ametyst, Amnethyst, Amthyst or Amythist are therefore incorrect.
