Fine Celestine specimens have been obtained from many localities worldwide. Blue and white crystals are found in Italy associated with bright yellow Sulfur
crystals in the famous Sicilian mines of Cattolico, Agrigento, Floristella, and Caltanissetta. Another locality of Celestine associated with Sulfur is the Machow Mine, Tarnobrzeg, Poland.
Several important Spanish localities for this mineral are known, especially Puente Tablas, in Andalusia; Tora, in Catalonia; and Arneva, in Alicante. Fine crystals once came from Yate in Gloucester, England. Beineu-Kyr, Turkmenistan, is an uncommon yet desirable source of this mineral in the form of
tabular and
platy white crystals with red
inclusions.
Enormous blue Celestine crystals, some in
geodes, are found in Madagascar, in Sakoany, Mahajanga Province. Red Celestine which at one time was thought to be
Barite comes from the Hammam-Zriba Mine, Tunisia. Other African localities are Jabal Akhdar, Libya; and the Wessels Mine, Hotazel, South Africa.
In Canada, Celestine comes from the Lafarge Quarry, Dundas; and from the Deforest Quarry, Inglewood, both in Ontario. In Mexico, Celestine is found in the Mojina Mine, Ahumada, Chihuahua; and in the Tule Mine, Melchor Múzquiz, Coahuila.
Some of the best specimens of Celestine mineral are from the United States. The
type locality and earliest occurrence is Bell's Mill, Bellwood, Blair Co., Pennsylvania, where it was found in
fibrous veins. Another important Pennsylvania locality is the Meckley's Quarry, Mandata, Northumberland Co. A historic Celestine occurrence is Lockport, Niagara Co., New York, where this mineral was discovered while digging the Erie Canal. There are several other Celestine localities in central New York, especially Chittenango Falls, Madison Co; and Walworth, Wayne Co.
The state of Ohio contains perhaps the greatest deposits. Especially of note is South Bass Island in Lake Erie, where giant pale blue crystals were obtained in the hamlet of Put-in-Bay. Also in Ohio are Lime City, Portage, and the Pugh Quarry, all in Wood Co.; and Clay Center, Ottawa Co., where the Celestine occurs with pale brown
Calcite and
Fluorite.
Michigan contains well-known Celestine deposits in the Maybee and Scofield Quarries (near Maybee), and at the Newport Quarry, Monroe Co. Other U.S. occurrences are the Annabel Lee mine, Hardin Co., Illinois; Bull Creek, Austin, Travis Co., Texas; and Death Valley, Inyo Co., California, where it occurs as large, colorless crystals associated with
Colemanite in
geodes. Celestine in geodes is also found in the Summerville and Curtis Formations, Emery and Wayne Cos., Utah.
