Here is a beautiful wulfenite specimen from an old and historic locality – Mezica, Slovenia.   It has large and very sharply defined crystals, in both a tabular and rectangular shape.  The color is a lovely butterscotch yellow, which is typical of the locality. Most specimens from here have crystals that are jumbled together in a solid mass. This piece has nice individual crystals, perched on the matrix and partially filling a vug.  This is an old specimen from my own collection which I acquired in 1990, but it dates back to the 1970s.
