specimen number:
2062498

location:
Maybee Quarry, Monroe Co., Michigan, USA

description:
A light blue lustrous and gemmy crystal of Celestine 3.5 cm across set perfectly within the center of a limestone matrix with golden crystals of calcite to 2.0 cm. The calcite crystals are lustrous and show good translucency. In very good condition overall. Collected in 1999.

The Maybee Quarry in Monroe County, Michigan, dates back in history to the 1850s, initially operating as a source of building stone and later becoming widely known among mineral collectors before it was abandoned and flooded prior to World War I; it was subsequently drained and put back into production around 1960, and it continues to operate today under modern ownership as part of the Stoneco aggregate operations. Geologically, the site features sedimentary rock strata containing significant deposits of limestone, alongside notable occurrences of native sulfur and celestine crystals formed through unique geochemical reduction processes within the local sedimentary layers.
