Excellent example of the alteration of white Montebrasite by blue Scorzalite, Brazilianite and Kulanite. Note the outer "skin" of the specimen in the fourth and fifth photos. Montebrasite-Amblygonite typically alters to a brown Kaolinite and the specimen will have smooth rounded edges produced during the alteration process. The name "nodule" is given to the masses of Montebrasite-Amblygonite.
