Celestine SrSO4, Calcite CaCO3
Description: Vug of sword-shaped celestine crystals, with excellent luster and sky-blue color, coated by small white creamy hedgehoglike calcite crystals. The specimen is an Autumn 2007 and exceptional find in the same locality as old findings in Torà, but the new specimen’s quality is much better. A specimen purchased a long time ago (in 2008) that is only interesting for local collectors.

Mass: 95.2 g.
Locality: Costa de l'Aguda, Torà, Solsonès, Catalonia.

The publisher of the 2025 Colors of Europe Calendar, issued yearly by Lithographie LTD, has given me the privilege of selecting for the next year one of my specimens to illustrate one page. Gloria Staebler has been very kind to allow me to post these photos here in advance, since the calendar will not be available until the next few weeks. It also includes an image of an impressive Schneeberg proustite owned by Joan Massagué, who is an FMF member too.
Species: Fluorapatite Ca5(PO4)3F, Siderite FeCO3 Dimensions: 38 mm x 24 mm x 20 mm
Mass: 20.2 g

Purchased in 1966 from Francesc Coma Molist (former curator of the Folch collection) for €0.18. The specimen was later treated by me with HCl (aq) to expose the celestine crystals that were almost enclosed in the calcite matrix.

A specimen that may be interesting only for local collectors.
