Description

A huge, very clear Marienglas selenite crystal from Brazil, Rio Grande do Sul, Irai. The elegant tabular geometry and exceptionally high transparency make this piece a premium example from its deposit.

Marienglas is the optically clear tabular variety of selenite, calcium sulfate dihydrate (CaSO₄·2H₂O). Material of this block size and clarity indicates a premium selection due to the deposit. Typically, Marienglas plates are significantly smaller.

The Irai deposit in Rio Grande do Sul provides the world's largest and clearest Marienglas plates. The history of the deposit dates back to the early 20th century.

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

A Brazilian collector's item with documented Irai provenance, premium clarity, and gallery dimensions.
