A 2.3 cm octahedron with stunningly mirror like luster and incredibly smooth faces is centered among the calcite\u002Faugite\u002Fhendricksite matrix. On a side note, hendrickite is the only Zn-dominant mica currently known, which makes sense as it's associated with gahnite, essentially a Zn-dominant member of the Spinel Group. Gahnite is rarely found in crystals this size that aren't distorted, rounded, \"lumpy\"\u002Fetched or just plain crude looking from any locality in the world. I've seen some sharp crystals from the Passaic Pit, and I've seen some lustrous crystals, but never have I seen both qualities combined in a gahnite like this one. With strong lighting, you can flashes of deep emerald\u002Fchrome green on the surface, so the crystal is not black.

A 2.3 cm octahedron with stunningly mirror like luster and incredibly smooth faces is centered among the calcite\u002Faugite\u002Fhendricksite matrix. On a side note, hendrickite is the only Zn-dominant mica currently known, which makes sense as it's associated with gahnite, essentially a Zn-dominant member of the Spinel Group. Gahnite is rarely found in crystals this size that aren't distorted, rounded, \"lumpy\"\u002Fetched or just plain crude looking from any locality in the world. I've seen some sharp crystals from the Passaic Pit, and I've seen some lustrous crystals, but never have I seen both qualities combined in a gahnite like this one.
