Calcite on Galena & Dolomite - Sweetwater Mine, Missouri, USA

An attractive calcite on galena and dolomite specimen from the Sweetwater Mine, Missouri, USA, recently obtained from the Bill Rouslin collection.

This substantial specimen features a striking arrangement of large, translucent calcite crystals displaying soft honey-yellow, cream and pale champagne tones. The crystals exhibit broad, reflective faces and well-developed terminations, with several prominent crystals projecting outward at different angles. Their overlapping arrangement creates an impressive three-dimensional composition, while subtle internal cloudiness and variations in transparency add visual depth.

The calcite crystals rest on a contrasting matrix of metallic grey galena and pale, finely crystallized dolomite. The combination of substantial calcite crystals and the textured mineral matrix creates an appealing contrast between smooth, lustrous crystal faces and sparkling granular surfaces.

The Sweetwater Mine is a classic Missouri locality known for its calcite and associated lead-zinc minerals. With its generous crystal size, attractive natural coloration and well-balanced mineral association, this specimen makes an impressive cabinet display piece and a desirable addition to a classic American mineral collection.
