Uralite is not actually a valid species. It is used to describe a pseudomorph of a hornblende group mineral after a pyroxene group mineral. In the case of this specimen, Actinolite after Diopside. Most of the Uralite crystals are small, long and thin but there are also larger more blocky crystals. The Uralite is a grayish green color and has a good luster. Also present, there are crude rounded crystals of Epidote crystals which are a brighter green color. There is also some white Calcite with a smooth glossy surface which appears to have been acid etched which is often done with specimens from the location to expose the Uralite. The specimen is in good condition   but some of the smaller crystals are undoubtedly missing - but it is hard discern.
