Absolute Stunner … Smoky Quartz Gwindel from Chamonix Mont Blanc, France
Smoky quartz gwindels from Chamonix-Mont-Blanc, France, are highly prized, rare, and distinctive twisted Alpine crystal specimens. They are characterized by parallel, side-by-side tabular smoky quartz crystals that exhibit a unique helical twist, often accompanied by chlorite inclusions, high luster, and exceptional clarity, frequently sourced from areas like Les Droites.
Key Characteristics & Details:
Appearance: These specimens feature a “twisted” or “swirled” growth habit (a “gwindel”) around the C-axis, which is a structural, not environmental, characteristic.
Color & Luster: They range from light to rich chocolate smoky colors, often with brilliant, glassy luster.
Inclusions: Many, particularly those from the French side of the Mont Blanc massif, contain chlorite inclusions that provide a matte, frosted, or “twisted” texture on the prism faces, while the termination faces remain clear.
Location: While often associated with Switzerland, notable, rare specimens are found in the Chamonix-Mont-Blanc area, particularly at Les Droites.
Form: Gwindels are classified as closed (tightly packed), open, or intermediate based on the tightness of their twist and separation.
Value: Due to their rarity and specialized, manual harvesting, they are considered high-end, collectable specimens, with prices generally higher in Europe.
These raretwisted crystals from the French Alps are famous for their aesthetic”windowpane” transparency and unique habit.
