Norwegian Thulite Gemstone
Hailing from the chilly north, Norwegian Thulite provides an inviting glow to warm you with its pink, white and red hues.
Norwegian Thulite is a variety of the gemstone zoisite, placing this stone in the same family as tanzanite. Due to the presence of manganese, Norwegian Thulite possesses an intense pink to red color. The presence of white calcite leads to its frequently seen mottled appearance, resulting in the display of pink, white and red tones throughout specimens of this gemstone. As this gem is opaque in appearance, it is most often shaped into cabochons or carved as small, ornamental objects.
Thulite can sometimes be confused with rhodonite. Generally, rhodonite is darker and is sometimes included with dark minerals. Surface oxidation can also alter the color of this material, providing a brown tint.
Rhodochrosite is another stone that is sometimes mistaken for thulite. The distinctive banding of rhodochrosite makes it easily distinguishable from thulite, however.
• Norwegian Thulite receives its coloration from the presence of manganese. As a variety of zoisite, it is related to tanzanite and anyolite (also known as ruby zoisite).
• Norwegian Thulite is named after the mythical island of Thule, believed in modern times to be Norway, Greenland or Iceland. For most of Medieval Europe, it represented the furthest known northern borders of the world. Knowledge of Thule dates back to antiquity and was first recorded by the Greeks between 330 – 320 BC. The term Ultima Thule grew from this, the ancient world's version of a pipedream. Besides being known as Norwegian Thulite, the stone is sometimes described as rosaline. The basis of the name lies in the gem's rosy color.
• In addition, thulite may also be known as manganoan zoisite. The name derives from the manganese content, which provides the stone's pink color.
Anders Gustaf Ekeberg
• Anders Gustaf Ekeberg first discovered this stone in Norway, in 1820. Ekeberg was a Swedish chemist who contributed several discoveries to our understanding of minerals.
Norwegian Thulite was first discovered in the early 19th century, in Telemark, Norway. Gem-quality deposits have also been found in Austria, Australia, and the Unite States. The primary source of this gemstone is still Norway, however.
Quaint and unassuming, the village of Sauland is known for being the area where thulite was first discovered. It's nestled in the rolling land of Telemark, a county of Norway. Rock croppings and valleys make the land difficult to navigate.
Nearly two hundred years ago, the stone was dug up near the present-day Øvstebø and Kleppan farms. Anders Gustaf Ekeberg, a Swedish chemist, is credited with its discovery.
Besides the production of thulite, the region is also a large supplier of gravel. The gravel is used in various construction and development projects throughout the country.
Also, besides being famous for thulite, Sauland is also the home to cyprine. Cyprine is a blue variety of vesuvianite, owing its color to the presence of copper.
During modern times, Norway is still the primary producer of thulite. Most material is sourced from Tvedestrand and Leksvik in Sorlandet, Aust-Auger. They are located to the southwest of Sauland, Telemark.
