Description

A very clear muscovite selenite crystal from Irai in Rio Grande do Sul, Brazil. Tabular cleavage planes, high transparency, calm internal shimmer.

Muscovite is the optically clear tabular variety of selenite, a calcium sulfate dihydrate (CaSO₄·2H₂O). It crystallizes from saline sedimentary solutions over long periods. Its historical use as a window material in sacred architecture gave the mineral its name.

The Irai deposit in Rio Grande do Sul provides the largest and clearest muscovite sheets in Brazil. Material of this clarity is a premium classification due to its deposit conditions.

Selenite is soft (Mohs 2) and water-soluble. Cleaning should only be done dry. The high transparency allows for backlighting with dramatic light refraction at the crystal cleavage planes.

A Brazilian collector's piece with documented Irai provenance, premium optical clarity, and clean tabular geometry.

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.
