This is a combination specimen. On one side of this piece, the matrix is covered with radial clusters of pyrophyllite to 0.1" (0.3cm). In a cavity on the other side of the specimen are rude crystals of svanbergite. No details of the hexagonal form of svanbergite can be seen; only rough crystal faces are present. There is no damage to this specimen.

The quartz matrix of this specimen is liberally strewn with tiny pseudocubic crystals of svanbergite. These crystals are honey in color, and some may be seen to be translucent (with the aid of a loupe). There is an unidentified crystal of some type on the back of this specimen. There is no damage to this piece. It is securely glued to a clear acrylic base.

The yellow, translucent crust along the top of this specimen is the svanbergite. The matrix upon which it rests is mostly a green translucent and quite hard mineral which I can't identify. The accompanying documentation said "fluorite and andalusite", and while the color does remind me of fluorite, the hardness is more like andalusite, but it could just be a green quartzite from it's appearance.
