A cabinet specimen of olmiite and bulfonteinite on matrix. 

For a long time these were believed to be poldervaartite, but were recently discovered to be the new mineral olmiite.  For more information, see the latest Mineralogical Record.

The reverse has crystals as well, larger and less clustered.  A very beautiful specimen.
