Be2(PO4)(OH)·4H2, KFe3+2(PO4)2(OH)·2H2O on Ca2Mg5Be4(PO4)6(OH)4·6H2O and NaBePO4
This specimen is composed of four, relatively rare, beryllium bearing phosphates. The Moraesite is present as thin, white to off-white colored, radiating, needle like crystals covering much of the surfaces. In places, there are spherical aggregates of green/brown colored Zanazziite (near the top of the specimen in the photos of the full specimen). There is a little bit of Leucophosphite covering some of these Zanazziite aggregates present as a white colored, earthy material. The underlying matrix is composed of an unidentified earthy brown colored material which has a few embedded, blocky of sections white colored, massive Beryllonite.
Flaws: There are areas where the matrix is exposed.
