A large geode with selenite crystals and pink anhydrites from Brazil, Rio Grande do Sul. Glass-clear selenite plates stand next to pastel-pink anhydrite aggregates, both calcium sulfate modifications in a single cavity.
Selenite (CaSO₄·2H₂O) and anhydrite (anhydrous CaSO₄) are two polymorphic calcium sulfate modifications that crystallize under different water availability conditions. The constellation in a geode documents changing solution conditions over the growth phases.
Pink anhydrites with selenite in a single geode are a top collector's item due to the deposit. The Rio Grande do Sul deposit provides the highest quality material worldwide for such multi-sulfate constellations.
Selenite is soft (Mohs 2) and water-soluble; cleaning should only be done dry. The gallery dimension demands its own museum display case.
A Brazilian museum-quality collector's item with two-sulfate genesis, gallery dimension, and top classification.
Wir beziehen unsere Kristalle direkt aus den Minen, ohne Zwischenhändler. Mehrmals im Jahr sind wir persönlich vor Ort und kennen die Familien, die diese Steine zutage fördern.
Sie erhalten einen fairen Preis für ihre Arbeit. In unseren Minen arbeiten ausschließlich Erwachsene unter sicheren Bedingungen, und davon überzeugen wir uns bei jedem Besuch.
Wie das vor Ort aussieht, zeigen wir in einem Film, der bei uns im Museum läuft.
Selenite is water-soluble. Do not clean with water. Only dust dry with a soft cloth.
