Spinel Law Twin Fluorite from Erongo, Namibia
Spinel law twinned fluorite, especially from the Erongo Mountains of Namibia, is a highly prized and rare mineral specimen. These crystals are known for their unique spinel twinning, often exhibiting vibrant colors and inclusions of Schorl (black tourmaline). The Erongo region is particularly famous for producing these distinctive fluorite specimens.
Here’s a more detailed look:
Spinel Twinning:
Spinel law twinning in fluorite refers to a specific crystal growth pattern where two fluorite crystals are intergrown in a mirrored fashion along a twin plane. This results in flat, tabular crystals with unique shapes.
Erongo Mountains, Namibia:
This region in Namibia is renowned for producing exceptional spinel-twinned fluorite crystals.
Color and Inclusions:
The fluorite from Erongo can display a range of colors, including green, purple, and even yellow, often with color zoning. A common inclusion is Schorl (black tourmaline), which can be found both within the fluorite and growing on its surface.
Rarity and Value:
Spinel-twinned fluorite from Namibia is considered rare, especially specimens with good clarity, color, and interesting inclusions. This rarity contributes to their high value among collectors.
Unique Features:
Some of these fluorite crystals also exhibit liquid inclusions (enhydros) that move within the crystal when manipulated, adding to their unique appeal.
