Here we have a super cluster with tetragonal Helvite crystals, accompanied by less, black Magnetite. This is a world-class mini of Helvite by any standard. It is a super cluster measuring 4,3 cm, across. It is, I think, complete, front side and rear are pristine so far I can see to the naked eye. All crystals are superbly defined, sharp edged and showing great luster. The three-dimensionality of the display side is very striking. Small Magnetite crystals aside the matrix make for a nice accent, as well.
