Amethyst is mother nature’s classy version of a quartz crystal!
They are visually stunning and have been in demand for many centuries. Its name derives from the Greek "amethystos", which means
"not drunken", as Amethyst in ages past was thought to ward off drunkenness. This gemstone is also said to protect its wearer against
seduction. Moses described it as a symbol of the Spirit of God in the official robes of the High Priest of the Jews. If this stone were not so
readily available it would be extremely expensive based upon demand.
The color of some Amethyst may slowly fade upon constant exposure to light. Amethyst changes color when it is heated. Amethyst is
sometimes heat treated to deepen its color, or to transform it into Citrine. The color of certain varieties can change to a light green color,
which is called "Prasiolite". Smoky colored stones can be transformed to a yellow to brownish-red and clear ones may become yellow. The
natural geothermal heating sometimes creates multi-color stones, like the specimens found in Bolivia, a variety called Ametrine. One of
the best websites we have found to help "Identify the Location" your specimens came from is

They have an excellent section describing the specimen formations from most of the source locales for Amethyst.

Uruguay Amethyst from the Artigas area is the most sought after locale. The specimens from Artigas are more pure and a deeper,
richer color than most finds. Artigas amethyst is found as vugs deep in hard rock base and requires major excavation to find the geode
like vugs of amethyst. Until 1999 this amethyst was hand dug or excavated with small machinery. Specimens have been sold through Idar-
Oberstein German markets for many years.
Brazilian Amethyst crystals are attractive to look at and form in drusy coatings that line the inside of sometimes large volcanic pockets
or “vugs”. Some of the vugs form from trees that were engulfed in a lava flow while other vugs are gas bubbles trapped in the lava.
Brazilian vugs can be very large and form crystals that are pale lavender to dark purple in color. The quality of these for gemstones is not
as good as others due to the fact that the color is not consistent throughout the crystal but is on the outer surfaces and on the tops of the
crystals. Most clusters form with gray, white and blue agate and have a green exterior on the vugs. Inclusions of calcite and cacoxenite
are common.
African Amethyst crystals are usually large but not as attractive as Brazilian Amethyst. However, the interior color and clarity are
excellent and polished slices and carvings as well as many gemstones from Africa are prized and admired. Colors range from very pale
lavender to a very dark purple. Most of the South African Amethyst is formed in vugs of white or tan, to light grey basalt.
Thunder Bay, Canada Amethyst has a distinct red hematite inclusion just below the surface of the crystals. This characteristic is unique
to this locality. Crystals are normally drusy coatings that line or fill the fissures that develop in metamorphic rock during its formation.

Smoky Amethyst Quartz Reel Mine
Lincoln County N.C.

$129.00
This is a Rare Amethyst Cluster from the Classic Locality, the Reel Mine (aka Reel Amethyst Mine) located near Iron
Station, Lincoln County, North Carolina.
Specimens from this location are very hard to come by. The crystals have
superb glassy luster and are very richly piled up and set off by the largest crystal forming at the top. Old Timers called
this "Real Mine Amethyst", but this is more correctly referred to as Smoky Amethyst Quartz. It is basically Smoky Quartz
with Amethyst Phantoms. There is a beautiful combination of smoky and amethystine hues, and the crystals have
enough clarity to see this beautiful color mix. This piece came from a 1950 to 1978 estate collection (see old sticker on
bottom of display case). It is glued down to Styrofoam and set in a 2-1/2" display cube. The weight listed excludes the
weight of the display cube. This is a highly sought after specimen from this classic location...not another one like it!

Reel Mine (aka Reel Amethyst Mine) near Iron Station, Lincoln County, North Carolina
The Reel Mine was mined years ago for amethyst for abrasives. This world class mine located in
the Western North Carolina Mountains was once mined by Tiffany and Company for gem grade
amethyst. Some of the finest North American amethyst was recovered from this location over
many years.

On November 4, 1972, Lewis Sigmon, in the Reel Mine in Iron Station, North Carolina,
discovered the largest amethyst cluster ever found in North America which is two feet long, two
feet wide and one foot high; it weighs a massive 165 pounds. The intense purple pigment of the
gem (which has been compared a glass of grape juice held up to sunlight) is as remarkable a
feature as its size and is a result of manganese dust, a characteristic of the mine from which the
amethyst came. This famous Amethyst cluster currently resides in the Grandfather Mountain
Nature Museum in Linville, North Carolina.

It was actually a fee-based operation where rockhounds could dig until an altercation prompted
the owners to shut it down. The mine has been closed to collectors for a number of years.
