Description
During the research for species and matching locale I was a bit confused,- the original label of Erberto Tealdi says Åkermanite from San Rocco of Lazio, Italy, but this species is not listed at the locale on mindat. Finally the Melilite specimens from there are looking similar to the specimen we see here; but in petrology "Melilite" usually refers to minerals in the Åkermanite-Gehlenite series, by far the most abundant members of the group.(mindat) However,- here we have a bunch of glassy white-grayish crystals in a vug. Added to Erberto Tealdis collection in 1980.
