Zincohögbomite-2N2S is a rare complex oxide mineral belonging to the högbomite group, characterized by a high zinc content. It is typically found in high-grade metamorphic rocks as small, dark, tabular crystals that can be difficult to distinguish from spinel without chemical analysis.
Is this zincohögbomite-2n2s?
5-step field checkRun through these checks against the specimen in your hand. The more boxes tick, the more confident the ID.
- 1Test the hardnessTry to scratch zincohögbomite-2n2s with a known reference. Zincohögbomite-2N2S sits at Mohs 7, softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Streak: brownish.
- 3Read the lusterHold the specimen under a strong light. Luster: adamantine.
- 4Match the color rangeCompare against the expected color range: deep brown, black.
- 5Look at form & habitCrystal system: hexagonal. Typical habit: euhedral crystals, pseudo tetragonal.

Field-hunting tip
Where it forms: Formed by breakdown of gahnite in diasporites (diaspore-bearing metabauxites) and emeries (corundum-bearing metabauxites). If you start seeing spinel, magnetite, corundum in float, you are in the right ground. Typical habit: euhedral crystals, pseudo tetragonal. Train your eye for that shape before scanning the outcrop.
