Grishin proposed a fitting name for the pegmatite: the Palitra (in English, "palette"), in allusion to the large pods of brightly colored minerals (red villiaumite, pearly-white natrosilite, green aegirine, lilac ussingite, lemon-yellow vuonnemite, crimson sodalite, orange eudialyte, salmon-pink serandite, dark-brown lomonosovite and lorenzenite, etc.
Associated minerals are: quartz, K-feldspar, vanadium-dominant mangan-neptunite, suzukiite, roscoelite and serandite.
Associated minerals are: microcline, nepheline (partially altered to natrolite), fluorite, natrolite, gonnardite, rhodochrosite, aegirine, albite, calcite, serandite, ancylite-(Ce) and catapleiite.
The new specimens, though, are entirely different: they consist of sharp, simple hexagonal-tabular epididymite crystals to 6 mm across, attached loosely in sugary white, jumbled groups, or skewered in neat little rows on black needle-crystals of aegirine, or draped over crystals of albite and/or serandite.
Associated minerals are: aegirine, epistolite, sphalerite, steenstrupine-(Ce) and altered serandite.
