Cactus Drusy Quartz (Spirit Amethyst) Cluster
Cactus Drusy Quartz (Spirit Amethyst) is found only in the Magaliesberg Mountain Range in the Gauteng Province near Pretoria, South Africa. It's unmistakable formation of a main crystal covered with smaller drusy Amethyst colored crystals make this one of the most beautiful natural Amethyst Quartz specimens available. It was called "Spirit Quartz" or "Spirit Amethyst" by the South African tribal medicine men who used them for healing rituals. This superb specimen has multiple definite points with a beautiful lavender drusy covering. It also has the beginnings of more points visible from the bottom of this piece. It is complimented by multiple botryoidal shaped formations that are the
beginnings of even more points.
The Magaliesberg is one of the oldest mountain ranges in the world at 2300 million years old, or 100 times the age of the Himalayas. The Magaliesberg Mountain Range is located in the Gauteng Province near Pretoria, South Africa. The small crystals that encase the bases of larger crystals identify Magaliesberg crystal, which forms as Quartz, Amethyst, Citrine or Ametrine, or even sometimes as a combination of these. The variations in formation are probably due to the age of the Magaliesberg, and the fact that this range is considered to be "the cradle of humankind".
Amethyst derives its name from the Greek word "amethystos" meaning "not drunk" or "not intoxicated". It is one of the favorite gem-quality minerals found in the Quartz family. Its color ranges from light lilac or lavender to the deep, rich, dark purples and violets...the latter (named Siberian Amethyst) being the most sought after, especially when containing flashes of red. The lighter lilac and lavender specimens of Amethyst have been nicknamed "Rose de France" by the gem trade. Experts believe Amethyst gets its color from trace amounts of Iron (other theories attribute it to Manganese or hydrocarbons) present during the formation of the Quartz. It is stated that "as much Iron as would fit on the head of a pin can color one cubic foot of Quartz."
Amethyst is formed in silica-rich liquids deposited in gas cavities (geodes) in lava. It occurs in crystalline masses. When conditions permit, it forms hexagonal crystals that are usually grown from a base. These crystals are most often not well developed, and so are generally found as clusters of crystal points and are called Amethyst Drusy. Although most commonly found in geodes, Amethyst is sometimes found as a stalactite. When heated, Amethyst loses its color, so it is best to keep these crystals from extended exposure to the sun. If heated intensely, the purple color of Amethyst will change to yellow...thus making it Citrine. Most commercial Citrine is made in this manner. When natural Citrine and natural Amethyst grow together in the same crystal they normally contain alternating bands of purple and orange/yellow and have been given the name Ametrine.
