Description

<p>An extremely rare mineral and a classic european locality: a rich and very good specimen with lots of bright yellow sulphur crystals on vuggy limestone matrix, partly covered by small and tiny whitish cubes and slightly brownish aggregates of the very rare 'semi-organic' SiO2 mineral melanophlogite. Really hard-to-get classic from Sicily.</p>
