A showy and excellent CABINET specimen of lustrous and glassy, blue-gray celestine crystals to 3.9 cm aesthetically filling a large vug in limestone matrix. This fine piece hails from the famous Meckley's Quarry of Mandata, Pennsylvania. The quarry opened in 1936 and this is large old-timer. The quality rivals Maybee, Michigan material. Ex. George Feist Collection.
