RM2649   Andradite, andradite-grossular

Fra Joan area, Costabona Mt., Setcases, Girona, Catalunya, Spain

Group of andradite crystals with the dominant forms of the dodecahedron. Intense color and good size. Partially corroded by fluids. Specimens from this mine have been analyzed indicating that it is andradite, although zonation with grossular cannot be discarded. Included in the matrix we can see some scheelite crystals. The Fra Joan area is a classic of Catalan mineralogy, located at an altitude of more than 1,600 m, a mineralization associated with a skarn. Specimens of this size are difficult to find.


Size: 8.6 x 6.7 x 5.5 cm.
Main crystal: 1.6 cm.
Found in ca. 1980's.
