I grabbed this out of recent production on its way out the famous Ojuela mine. Good solid pieces like this one don't last long, compared to partial and broken pieces. Wulfenites as well as Mimetite specimens have recently been found here following a prolonged draught that lowered the water table low enough to allow mining in these previously flooded zones. Recently the mine has re-flooded, and there are some questions about financing further mining operations here. This piece is bright and in superb condition.
