Milarite is a beryllium silicate, the first described member of what later became the milarite group (Hawthorne et al., 1991). The name comes from Val Milar (Kenngott, 1870), adjacent to the actual type locality of Val Giuv, Swtizerland (Roth, 2007).

Milarite here forms yellow-green hexagonal prisms, deeply rooted in matrix, barely extending above the surface of the specimen. The largest hexagonal termination measures 7 by 6 mm across, and is centered in matrix of orthoclase feldspar (variety valencianite) with minor quartz and dolomite. Such material dates to the early 1970s, and may have been a single find.
