{"product_id":"min3055calcite-chalcopyrite","title":"Calcite \u0026 Chalcopyrite","description":"Fine calcite crystal specimen from the Sweetwater Mine, Reynolds County, Missouri, featuring a well-formed prismatic crystal with termination displaying pale yellow coloration and good translucency. The crystal exhibits clean prism faces with visible striations and a lustrous surface, standing prominently from a substantial dolomite matrix. The matrix itself is noteworthy, studded with numerous small chalcopyrite crystals that display characteristic brassy metallic luster. This attractive combination of species demonstrates the classic mineral association from this historic Missouri locality. The specimen displays natural aesthetics with the calcite's vertical orientation providing strong visual appeal against the crystalline matrix.
