    Description

    Montgomeryite
    Tip Top Mine (Tip Top pegmatite)
    Fourmile, Custer District, Custer Co.
    South Dakota, USA
    2.91 x 1.66 x 1.16 inches (7.40 x 4.22 x 2.95 cm)

    The secondary mineral Montgomeryite is quite uncommon and occurs this time with Robertsite and Englishite, which are also rarer species. This "3-for-1" is a must for collectors and hails from the type locality for the some ten different minerals known in this pegmatite outcrop from the Tip Top Mine.

    Provenance: Central Coast Collection

    [Scale: 1 inch, with mark at 1 cm]
