Collection: Tourmaline

Namibia is world-renowned for its exceptional tourmaline deposits. Few other mineral groups offer such an impressive range of colors and crystalline diversity. From the deep black, protective schorl crystals of the Erongo Mountains to the vibrant gemstones of the Kaokoveld, Namibian tourmalines are the centerpiece of any discerning mineral collection.

The world of tourmalines: One family, endless colors

Tourmalines are a complex group of silicate minerals that crystallize in the trigonal crystal system. They mostly form in pegmatites, where mineral-rich solutions form perfect columns and prisms over millions of years. In Namibia, we find two main regions that are famous for their first-class finds:

• Black Schorl (Erongo): Schorl is the iron-rich, black variety of tourmaline. Finds from the Erongo Mountains are distinguished by their deep black, high-luster finish and their often perfectly formed, prismatic terminal faces. They frequently occur in aesthetically pleasing combinations with white feldspar or clear quartz.
• Green Verdelite (Kaokoveld): The green tourmalines from the Kaokoveld region range from a delicate mint green to a deep forest green. Their transparency and color depth make them highly sought-after objects for collectors and gem cutters.
• Blue Indigolite (Kaokoveld): One of the rarest and most valuable varieties. These tourmalines display fascinating shades of blue and turquoise, often possessing exceptional brilliance.
• Pink Rubellite (Kaokoveld): These pink to reddish tourmalines bring warmth to any collection. Specimens with a clear color change or fine phantom structures are considered mineralogical treasures.

Special characteristics and care

With a Mohs hardness of 7 to 7.5, tourmaline is among the hardest gemstones. A fascinating physical property is its pyroelectricity: by heating or rubbing, the crystal can become electrically charged and then attracts fine dust particles. To ensure your tourmaline treasures continue to shine, you should follow these tips:

• Cleaning: Gently clean your crystals with lukewarm water and a soft brush. Avoid harsh chemicals to prevent damaging their natural brilliance.
• Storage: Because tourmalines often have fine, needle-like structures or internal stresses, they should be stored in a shock-protected manner. Separating them from harder gemstones like diamonds prevents scratches on the smooth crystal surfaces.
• Light: While schorl is very light-stable, some very bright colored tourmalines can easily lose intensity after decades of extreme sunlight. A display case with UV-protected glass is ideal.

Tourmalines from Namibia tell a story of extreme pressure and chemical purity deep within African rock. At Mineralodo, we personally select each piece to ensure you receive only the finest crystals directly from their source.
