NOT a Gaudefroyite! this one fooled us at first, too! It is a SUPERB mangan-vesuvianite with deep wine-red color when backlit, so you can be sure of the ID. This specimen features crystals of the highest quality and the best luster, almost glassy in brightness - rare for the species. There is some damage to smaller crystals, but most major crystals are complete, and the display is phenomenal. The matrix is sparkling, minutely crystallized andradite garnet. The large single crystal atop is doubly-terminated and almost 2 cm long tip to tip.
