Ferrohögbomite-2N2S is a rare complex oxide mineral belonging to the högbomite group, typically found in high-grade metamorphic terrains. It usually occurs as small, dark, tabular crystals often embedded within spinel-rich matrices. Identification typically requires advanced chemical analysis such as electron microprobe to differentiate it from other members of the högbomite supergroup.
Is this ferrohögbomite-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 ferrohögbomite-2n2s with a known reference. Ferrohögbomite-2N2S sits at Mohs 6 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Ferrohögbomite-2N2S leaves a brown streak.
- 3Read the lusterHold the specimen under a strong light. Ferrohögbomite-2N2S typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: dark brown, black.
- 5Look at form & habitCrystal system: hexagonal. Typical habit: tabular crystals.
Often confused with
Ferrohögbomite-2N2S vs. its common look-alikes — and how to tell them apart in the field.
How to tell apart: Spinel is the harder of the two (Mohs 8 vs. 6); streak differs — Ferrohögbomite-2N2S leaves brown, Spinel leaves white.
How to tell apart: Streak differs — Ferrohögbomite-2N2S leaves brown, Magnetite leaves black; luster reads vitreous on Ferrohögbomite-2N2S and metallic on Magnetite.
How to tell apart: Streak differs — Ferrohögbomite-2N2S leaves brown, Iron Ore leaves reddish-brown to black; luster reads vitreous on Ferrohögbomite-2N2S and metallic to submetallic on Iron Ore.

Field-hunting tip
Look in metamorphic rocks country — that is the host setting where ferrohögbomite-2n2s typically forms. If you start seeing spinel, magnetite, corundum in float, you are in the right ground. Field specimens usually show a tabular crystals habit, so train your eye for that shape before scanning the outcrop.
