This is an absolutely superb Wulfenite specimen from the famous Ahumada Mine of Los Lamentos, Chihuahua, Mexico. This is a real windo-pane-classic. A sharp and gemmy 1,4 cm crystal perfectly perched on typically gossan matrix. I have seen only a very few such fine Wulfenites over the years and all from old collections and most of them noted to be from the early 1900s. This clarity and colour together are unique - and were exceeding seldom found in modern times. The crystal is complete all around and some white Calcite crystals are perched on it. There are some prints of disolved Calcites as well. A super specimen.
