Celestine with Native Sulfur from Machów Mine, Poland

Colorless to clear celestine crystals sit on an intensely yellow matrix of native sulfur. The well-formed crystals display a distinct vitreous luster and create a striking contrast with the bright yellow sulfur.

The crystal group is freely arranged on the matrix and clearly displays the characteristic association of celestine and sulfur. The contrast between the transparent to translucent crystals and the strongly colored matrix defines the visual appearance of this specimen.

Historic Sulfur Deposit near Tarnobrzeg

Machów Mine near Tarnobrzeg in Poland’s Subcarpathian Voivodeship was an important open-pit sulfur mine. Mining ceased in 1992; the former mining area was later reclaimed and flooded. Today, Lake Tarnobrzeg occupies the former mine site.

Numerous mineral species have been documented from the deposit, including native sulfur, celestine, calcite, gypsum, quartz, and barite. The association of celestine and sulfur is one of the characteristic mineral assemblages of the locality.

Based on its actual dimensions, the specimen can be classified as either a miniature or a small cabinet specimen. Its particular appeal lies in the clear celestine crystals on the bright yellow sulfur matrix.
