An extremely rare Amethyst specimen, purchased in Brazil by Jack Lowell in 1973, on his first trip to Brazil, from the famous jewelry designer Haroldo Burle Marx. It began growth as a colorless enlongated prism, and at a later time formed a deep reddish purple tip with several smaller Amethyst crystals of the same color. It came from a pegmatite, which is a rare geologic origin for an Amethyst. Dave Daniel purchased it from us in 2004, and it is in the group of specimens from his collection that we are now selling. One of the best Quartz Jack has ever had. Impossible to find a similar crystal.
