Group of white albite blades surmounted by lepidolite on top of which two apparently twinned and very well formed crystals of red-brown tantalowodginite have formed. Perpendicularly to the face of one of these two crystals a perfect transparent 3mm crystal of tantalite-(Mn) has grown. A third tantalowodginite crystal has formed at the rear within the albite.
