This specimen presents a good size nodule, with an internal part with septaria structure, completely covered by very brilliant and transparent green crystals of this rare iron and calcium phosphate. In this specimen we can observe some white aggregates of fluorapatite. Anapaite nodules from the Bellver de la Cerdanya area are a classic of the Catalan and European mineralogy. The materials where these nodules appear are part of the filling of a deep lake of the upper Miocene that developed in the southern part of the Cerdanya basin.
