Wiluite from the remote Vilyui River Basin in Eastern Siberia was, for centuries, classified as a variety of Vesuvianite but was formally designated as a new species in the late 1990s. Specimens are so distinctive, with the dark olive-green Wiluite crystals forming perfect, doubly-terminated, tetragonal prisms embedded within a contrasting pale grey rock matrix. This miniature specimen presents a single, well-formed Wiluite crystal, 1.8 cm in length, perched on matrix. The crystal sits in such a way that two prism sides and one termination can be viewed and is an excellent example of this wonderful crystal form.
