Description

    CALCITE EPIMORPH AFTER ARAGONITE
    Cozzo Disi Mine, Casteltermini, Agrigento Province, Sicily, Italy

    Although the Hoppel catalog lists this as "Quartz after Aragonite", it is actually a Calcite epimorph after Aragonite. The proof is that the druzy epimorphic coating is not harder than steel and it fluoresces pink under U.V. Besides the above, the specimen exhibits the same form and epimorphic character as classic Cozzo Disi specimens: so the cited locality of Bubbonia Mine is wrong, too. That said, it is a great example from Cozzo Disi. The central "crystal" measures a whopping 3.25 inches (8.25 cm) across. There are other epimorphs but this is the only complete one visible. Condition is excellent - any damage is confined to the edges where the piece was trimmed down from a larger plate. The edges and back show blebs and crystals of Sulfur - another Cozzo Disi Mine feature.
    Overall measurements: 8 x 7 x 3 inches (20.3 x 17.8 x 7.6 cm).

    Provenance: Keith Proctor [Hoppel # D1818]


    Estimate: $4,800 - $6,000.
