Celestine & Calcite

This sharp blocky celestine crystal displays a light blue-gray translucency and a soft matte luster. Wisps of sulfur inclusions dance within the faces, while tiny white calcite growths nestle in subtle etch pits. Collected in April 2024 from Sylvania Minerals Quarry in Rockwood, Michigan, this classic specimen is rare due to limited annual access by only a handful of mineral clubs.
