Very clear selenite crystals from Brazil, Rio Grande do Sul, Irai in matrix. The tabular crystals are embedded in their original sedimentary matrix, a geological document in gallery format.
Selenite crystals in matrix document the original deposit geometry. Such matrix pieces are rarer than isolated selenite plates because they can only be recovered undamaged from the soft sediment.
Selenite (CaSO₄·2H₂O) crystallizes from saline sedimentary solutions over long periods. The Irai deposit provides the largest and clearest plates worldwide. The crystals visible here document slow crystallization under stable sedimentary conditions.
Selenite is soft (Mohs 2) and water-soluble; cleaning should only be done dry. Its high transparency allows for backlighting with dramatic light refraction.
A Brazilian museum-quality collector's item with documented deposit geometry, premium clarity, and significant gallery dimensions.
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.
