Celestine, Dundas Quarry, near Hamilton, Ontario

Phantom crystal, 20x13x2, perhaps my all-time fave, collected 05/1991

A top-notch Dundas celestine cluster, 65 mm across with doubly terminated xls to 45 mm long. Note the color zoning, feathery multiple terminations, and tiny marcasite specks, all typical for the locality. Image courtesy of Maggie Wilson

Closeup of the fuzzy termination... weird, anybody know the cause?

A neat specimen that gives a better idea of how these form and are found, in vugs in rock. 

The vug is 95 mm across, lined with small pale yellow calcites, and celestine to 15 mm
