Tourmaline is a crystal boron silicate mineral compounded with elements such as aluminium, iron, magnesium,
sodium, lithium, or potassium. Tourmaline is classified as a semi-precious stone and the gemstone comes in a
wide variety of colors.
There are three species and seven varieties of tourmaline that occur in various colors; pink, red or rubellite, green
tourmaline, blue or indicolite, black or schorl, watermelon and tourmalated quartz. The watermelon tourmaline is a
rare variety that displays three different colors in the same crystal - green (the skin of the watermelon), pink (the
watermelon fruit) and white (the rind). The colors of the watermelon tourmaline occur 100% naturally. This is a rare
occurrence in nature. Common species and varieties are;
Schorl species:                                     
           Brownish black to Black—Schorl
Dravite species:                                     
           from the Drave district of Carinthia
                   Dark yellow to brownish black—Dravite
Elbaite species:                                          
           named after the island of Elba, Italy
                        Red or pinkish-red—rubellite variety (from rubellus)
                                                  Light blue to bluish green—Brazilian indicolite variety (from indigo)
              Green—verdelite or Brazilian emerald variety
                                                Colorless—achroite variety (from the Greek meaning "colorless")
            Multi-color tourmaline's-watermelon, bi-color
Schorl
The most common species of tourmaline is schorl. It may account for 95% or more of all tourmaline in nature. The
early history of the mineral schorl shows that the name "schorl" was in use prior to 1400 because a village in
Saxony, Germany named "Schorl" had a nearby tin mine where black tourmaline was found in the Saxony Ore
Mountains.

Dravite
Dravite, also called brown tourmaline, is the sodium magnesium rich tourmaline end member. Uvite, in comparison,
is a calcium magnesium tourmaline. Dravite forms multiple series, with other tourmaline members, including schorl
and Elbaite. Dravite varieties include the deep green chromium Dravite and the vanadium Dravite.

Elbaite
A lithium-tourmaline is called Elbaite.  Elba Island, Italy, was one of the first localities where colored and colorless Li-
tourmalines were analyzed. In 1914 Vladimir Vernadsky proposed the name Elbaite for lithium-, sodium-, and
aluminum-rich tourmaline from Elba Island, Italy. The first crystal structure determination of a Li-rich tourmaline was
in 1972, performed on a pink Elbaite from San Diego County, California.

Tourmaline Crystals in Quartz

This brown Dravite Tourmaline specimen is from Yinnietharra Station, Pilbara
Region, Western Australia, Australia. It is from the Soklich open cut mine which
operated from 1968 to 1971. Dravite Tourmalines from this classic Australian
locale are generally considered to be among the world’s finest. Crystals from
this mine have graced collections for many years as examples of the crystal
habits of large tourmalines.

These crystals are a lustrous, rich root beer brown which appears opaque but
has minor translucence, a vitreous luster, often indented with small booklets of
mica. It is very rare to find specimens that have these mica inclusions. Some of
the specimens may be very large. They can occur as single and twinned
crystals, or they may be grouped. Crystals at the Soklich cut were found
sporadically within pockets. The best quality specimens like this were found
around 10 to 20 feet below the surface.

This piece weighs 7.9 oz or 0.49 lb (225g)
measures 2.2 x 2.2 x 1.6” (5.7 x 5.7 x 4.9cm)

Dravite-Uvite Tourmaline from Pierrepont, St. Lawrence County, New York
This is a lustrous black partial crystal of dravite-uvite tourmaline with no matrix
attached. Both uvite and dravite tourmalines occur at this locality, often both
species are within a single crystal which is why they should be labeled dravite-
uvite tourmaline. It was first found by a teenager in 1859. Since then many
specimens of lustrous black tourmaline crystals from Pierrepont have found their
way into both museum and private mineral collections worldwide. Pierrepont is a
classic American mineral locality and a popular site for field collecting.

This piece weighs 1.1 oz (32.5g) and measures 1.2 x 1.1 x 0.9” (3.1 x 2.8 x 2.4cm)

Dravite-Uvite Tourmaline from Pierrepont, St. Lawrence County, New York

Dravite-Schorl radiating Tourmaline (Tourmaline fans) from Mount
Grace, Warwick, Franklin County, Massachusetts.
This specimen has multiple lustrous thin black tourmaline crystals in fan-
shaped groups of radiating crystals in fine-grained hornblende schist.
Geologists studying Mount Grace cannot agree whether this is dravite or
schorl tourmaline. Because of this disagreement, it has been suggested that
these specimens be labeled dravite-schorl tourmaline. These tourmalines
absorb the iron from the surrounding rock, leaving a fine granular quartzite
slightly tinted by epidote.
This specimen was from the collection of the Rev. Douglas J Berndt of
Kingsport, Tennessee. The specimen is from Mt Grace in Warwick,
Massachusetts which is where his wife Susan Berndt attended college.
They lived in Massachusetts from the early 1940’s until they moved to
Tennessee in 1962.

This piece weighs 10.6 oz or 0.66 lb (302g)
and measures 3.7 x 2.9 x 1.4 inches (9.5 x 7.5 x 3.6 cm)
