A lead tellurite with one reported locality thus far. This specimen contains at least four snow white radial aggregates composted of minute fibers. The largest spherule is about 0.5mm. The green mineral is probably Emmonsite. It is not chlorargyrite as it is not soft and sectile and wrong crystal habit. It may be Rodalquilarite, but it also is the wrong habit, An excellent and rich specimen! Very rare.
