Carlhintzeite, Creedite

A very nice rich specimen of yellow acicular crystals of the extremely rare mineral carlhintzeit, a hydrated aluminum and calcium fluoride. This mineral was first described in the world from Hagendorf in Germany. However, the newly found samples from China are still the richest and most aesthetic specimens of this mineral. In this sample, carlhintzeit occurs with clear crystals of the also very rare mineral creedite.
