SV3260TGH:

A very rare species, Greifensteinite, which is a phosphate of calcium, iron, and beryllium, doesn't particularly stand out for its beauty. However, it has been fortunate to find excellent companionship as both Muscovite and Albite are pleasing and enhance the aesthetics of the less attractive Greifensteinite.
